1 Introduction
Over the past decades, researchers and commercialized have
focused on the organic light emitting diodes (OLEDs). These
materials have a wide application in electrical, electronic,
optical, optoelectronic and photonic technology due to its
crystal structure, optoelectronic properties, panel displays
and lighting applications, easy conductivity control, good
environmental stability, corresponding to the visible spec-
trum, its energy gap of 2.5eV and low cost manufactur-
ing in large quantities [17]. Also these materials have high
contrast, low weight, flexibility and they can be rollable
or foldable to meet several special needs [8]. These wide
possible properties can be realized by analyzing the basic
science in involved in the operation the physics of OLEDs.
Triphenylamine (TPA) and related derivatives are widely
used as three-dimensional conjugated systems of organic
semiconductors (OSCs) with superior performance trans-
porting/hole-injecting behavior or luminophore materials in
LEDs due to the non-coplanarity geometry of the three phe-
nyl rings [911]. TPA-based compounds have been widely
applied as electroluminescence and hole transport materials
[10, 1215] and their multifunctional and amorphous prop-
erties offer the possibilities to develop active materials for
organic fotovoltaic diodes and solar cells with charge trans-
port and isotropic optical properties [12]. On the other hand,
tris[4-(diethylamino)phenyl] amine (TDAPA) molecule is
used as a dopant of nanostructure film that it increasing car-
rier concentration [16].
In the present work, we investigated optoelectronic prop-
erties of TDAPA molecule for different solvents and molari-
ties. Also, the characterization of the TDAPA molecule was
theoretically performed by using the density function theory
(DFT) method, as well as in the use of the FT-IR, dispersive
Raman, UV–Vis measurements. Experimental and theoreti-
cal results were compared to better analysis. Investigation
of the spectroscopic and optoelectronic properties of the
TDAPA molecule is theoretically and experimentally impor-
tant for the formation of new OLED materials.

... It is generally established that charge-carrier transport is limited by hopping between molecules in the disordered region, and that molecular ordering must provide sufficient overlap of the p-orbitals of conjugated organic molecules to facilitate efficient charge migration between neighbouring molecules [14][15][16]. Organic molecules such as TDAPA are used as a dopant in nanostructure films to boost carrier concentration for organic optoelectronic devices such OFET [17][18][19]. Small molecule fluorophores are used in wide range of applications such as biophysics, molecular biology, medicine, and material sciences [20][21][22][23][24]. Such materials are widely adopted for the optoelectronic devices such as OFET and OLED, and to study their behaviour in different solvents is essential to understand its structural and electrical behaviour. ...
... The effect of different solvents, both Polar [Aprotic (DMF, Acetone and Acetonitrile) and Protic (Ethanol and Methanol)] and Non-Polar [Toluene and Chloroform] was explored using UV-Vis spectroscopy. The absorption spectrum of TDAPA in DMF and Chloroform was studied earlier by Tanis et al. [19]. In this study, the absorption spectrum of TDAPA in DMF and Chloroform is given in Figure 2, where for DMF absorption peak is observed at 263.7 nm and 320 nm and for Chloroform 281.8 nm, 318 nm and 404 nm, which suggest that in DMF solvent the absorption peak is in NUV (Near UV) and in Chloroform solvent peaks are in both NUV and Visible region. ...

Tris [4-(diethylamino) phenyl] amine (TDAPA) is an organic molecular semiconductor generally used to enhance the charge transport of the devices for some time now. TDAPA is dissolved in various Polar and Non-polar solvents like DMF, Acetone, Acetonitrile, Ethanol, Methanol, Toluene and Chloroform. Absorption spectrum of solution is recorded using UV-Vis spectroscopy and absorption peak for different solvents were observed in UV and Near-UV region. PL study and Pl Excitation study is also carried out for these solvents. Results for absorption and photoluminescence show some interesting phenomenon of Stokes’ shift. The colour coordinates for respective emission are represented by CIE 1931. The study is successfully carried out for better understanding of effect of these solvents on the optical properties of TDAPA.

This study demonstrates the charge transport properties of Tris[4-(diethylamino) phenyl]amine (TDAPA) in the frequency and temperature range of 0.1 Hz–1 MHz and 253–333 K, respectively using impedance spectroscopy. X-ray diffraction patterns of TDAPA powder and thin film indicate the polycrystalline nature of the studied material. The depressed semicircle in Nyquist’s plot indicates a non-Debye-type relaxation mechanism. The Almond-West power law and the Jump relaxation model were applied to investigate the charge transport and hopping mechanism. The exponent value was calculated and found well within range and the dc conductivity was determined using the same. Activation energy corresponding to dc conductivity and hopping was calculated and found to be 0.37 eV and 0.31 eV, respectively. The temperature-dependent behaviour of the exponent (s) is investigated in detail. The charge carrier mobility of TDAPA was also calculated by fabricating an organic field effect transistor in bottom gate top contact geometry on Si/SiO2 substrate. OFET characteristics of the material indicate the p-type behaviour with charge carrier mobility of 5.14 × 10⁻⁴cm²/Vs, 2.36 Vs, the threshold voltage of 33.61 V, and 2.19 × 10³ On/Off.

Since organic materials have applications in many fields, characterization and optical parameters of 3-(Biphenyl-4-yl)-5-(4-tert-butylphenyl)-4-phenyl-4H-1,2,4-triazole (TAZ) molecule have been investigated in different solvents. First, UV–vis spectra and optical parameters such as mass extinction coefficient (α mass ), optical band gap E g , refractive index n, optical and electrical conductance values have been also researched as experimental and theoretical. Also the most stable state, frontier molecular orbitals and Non-linear optical properties have been investigated with DFT methods and HOMO-LUMO energy range of TAZ molecule have been compared experimentally to the optical band gap. According to the results, it was seen that the TAZ material was suitable for opto-electronic applications because of its high refractive index and wide E g value.

We analyze the performance of bulk heterojunction organic solar cells under oblique incidence of light. In this regard, we present an optoelectronic analytical model that describes the current-voltage characteristics of bulk heterojunction organic solar cells taking into account the effect of angle of incidence. A closed-form general expression is derived for the optical generation rate under oblique incidence employing transfer matrix formalism. The resulting expression is then incorporated in the classical drift-diffusion transport and continuity equations of charge carriers to derive a unified expression of voltage dependent current density combining optical and electrical parameters. Thus, the model is capable of determining the accurate optical absorption in the active layer for varying angles of incidence as well as predicting the corresponding wavelength dependent external quantum efficiency of the device. The results are verified by comparing with published numerical and experimental results. We show that the maximum efficiency might be achieved at an oblique angle of incidence rather than normal incidence for certain active layer thicknesses. We also report the optimum angles at which the maximum efficiency occurs and show that they are active layer thickness dependent.

n this study, 4-(dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran (DCJTB) was achieved using the experimental and theoretical studies. The electronic, optical and spectroscopic properties of DCJTB molecule were first investigated by performing experimental both solution and thin film techniques and then theoretical calculations. Theoretical results showed that one intense electronic transition is 505.26 nm a quite reasonable and agreement with the measured experimental data 505.00 and 503 nm with solution technique and film technique, respectively. Experimental and simple models were also taken into consideration to calculate the optical refractive index of DCJTB molecule. The structural and electronic properties were next calculated using density functional theory (DFT) with B3LYP/6-311G (d, p) basis set. UV, FT-IR spectra characteristics and the electronic properties, such as frontier orbitals, and band gap energy of DCJTB were also recorded time-dependent (TD) DFT approach. The theoretical value were found to be 2.269 eV which is consistent with experimental results obtained from solution technique for THF solvent (2.155 eV) and literature (2.16 eV). The results herein obtained reveal that solution is simple, cost-efficient and safe for optoelectronic applications when compared with film technique.

In this paper composite materials, based on polymer blends of polyvinyl alcohol (PVA): polyvinyl pyrrolidone (PVP) with small optical band gap, has been studied. Silver sulfide (Ag2S) semiconductor particles have been synthesized in PVA:PVP blend host polymer, using in situ method. X-ray diffraction (XRD) analyses and Fourier transform infrared (FTIR) spectroscopy for the composite samples were carried out. From the XRD pattern, distinguishable crystalline peaks caused by the Ag2S semiconductor particles were observed. From the result of FTIR spectroscopy, the intensity of the FTIR bands were shifted and increased, revealing the occurrence of interactions between the PVA:PVP blend system and Ag2S particles. The composite samples were found to exhibit absorption spectra that cover UV–visible to near infrared regions. The absorption edge was found to be 5 eV for pure PVA:PVP system and shifted to 1.15 eV for incorporated PVA:PVP with 3 M of Ag2S. The refractive index was also evaluated for the samples and observed to be increased from 1.15 to 1.52 as doping increased to the highest. A linear relationship between the refractive index and the filler fraction has been reported. Theoretical discussion of optical dielectric loss, which is a crucial parameter for the band gap estimation, was given. The achieved results reveal that spectra of the optical dielectric loss (ɛi) can be used to study the band gap structure and Tauc's model can be important in determining the types of electronic transition. The optical band gap was found to decrease from 5.2 eV for the pure PVA:PVP to 1.1 eV for doped PVA:PVP with 3 M of Ag2S. Such reduction can be associated with the increase of optical dielectric constant. Finally, the correlation between optical dielectric constant and density of states was discussed.

In this article, the synthesis, characterization and use of two novel naphthalimides as electron-transporting emitter materials for organic light emitting diode (OLED) applications are reported. The molecules were obtained by substituting electron donating chloro-phenoxy group at the C-4 position. A detailed optical, thermal, electrochemical and related properties were systematically studied. Furthermore, theoretical calculations (DFT) were performed to get a better understanding of the electronic structures. The synthesized molecules were used as electron transporters and emitters in OLEDs with three different device configurations. The devices with the molecules showed blue emission with efficiencies of 1.89 cdA⁻¹, 0.98 lmW⁻¹, 0.71% at 100 cdm⁻². The phosphorescent devices with naphthalimides as electron transport materials displayed better performance in comparison to the device without any electron transporting material and were analogous with the device using standard electron transporting material, Alq3. The results demonstrate that the naphthalimides could play a significant part in the progress of OLEDs.

In this study, the electronic, optical and spectroscopic properties of 2-tert-Butyl-9,10-di(naphth-2-yl) anthracene (TBADN) semiconductor in different solvents were investigated by experimentally and computationally. Obtained theoretical and experimental UV-VIS spectra of the TBADN were found to be quite in good agreement and can be controlled with various solvents. Refractive index values of the TBADN semiconductor in different solvents were experimentally measured and calculated theoretically. Finally, the FTIR spectra of the TBADN organic semiconductor in different solvents were investigated by theoretical and experimental methods. It was found that the band gap is sensitive to the concentration of the solute.

In this study, polyaniline doped by boric acid (PAni:BA) conducting polymers were chemically synthesized by oxidative polymerization method using (NH4)2S208 (APS) as initiator. Pani:BA conducting polymers were synthesized by using two different APS/aniline molar ratios as 1:1 and 2:1. Their results were compared with PAni doped by HCl (PAni) conducting polymer. Structural properties of the PAni, PAni:BA (1:1) and PAni:BA (2:1) conducting polymers were characterized by using FTIR, SEM, TGA, particle size and apparent density measurements. Effects of doping agents and initiator concentrations on optical properties were investigated in detail. The optoelectronic parameters such as absorption band edge, molar extinction coefficient, direct allowed band gap, refractive index, optical conductance and electrical conductance of the PAni, PAni:BA (1:1) and PAni:BA (2:1) were determined. The absorption band edge and direct allowed band gap of PAni were decreased with doping BA and increasing APS ratio. Also, the refractive index values of the materials were calculated from experimental results and compared with obtained results from Moss, Ravindra, Herve-Vandamme, Reddy and Kumar-Singh relations.

In this article, a novel approach is presented for the preparation of small band-gap polymer composites. The intensity of the surface plasmon resonance (SPR) peak increased from 0.64 to 3.2 for the chitosan–silver nitrate sample containing 1 wt % titanium dioxide (TiO2). In the cases of 3 and 5 wt % added TiO2 particles, the SPR peak disappeared. A wide shift of the absorption coefficient from 4.36 to 0.93 eV was observed. The smallest optical band gap of about 0.98 eV was achieved for the sample containing 3 wt % TiO2 filler. The wide shift in the optical band gap was interpreted on the bases of the formation of metal-induced gap states between the metallic silver particles and the TiO2 structure. A novel approach was achieved that was an alternative method to Tauc's semi-empirical model for band-gap estimation. The optical dielectric loss parameter for the band-gap study was easily calculated and analyzed, whereas it unfolded a deep knowledge from the physics point of view. The established quantum mechanical expression revealed a strong relationship between the energy band gap and the optical dielectric loss parameter. The scanning electron microscopy results show the leakage of white aggregated silver particles and distinguishable intense peaks of metallic silver particles between 3 and 3.3 keV appearing in the energy-dispersive X-ray spectrum. © 2017 Wiley Periodicals, Inc.
