Measurements of resonance Raman scattering from single crystalline (or amorphous) particles suspended in an electrodynamic balance have been made for inorganic and organic microparticles, potassium permanganate (KMnO4) and p-nitrosodimethylaniline (p-NDMA), respectively. The microparticle dimensions were in the range 10-50 μm. The particles were ob...

... and Fung 18 reported that Raman shifts for the nitrate ion in the presence of different ionic species in salt particles can vary by over 20 cm 2 1 , but we do not see any statis- tically signi cant difference between the nitrate peaks of KNO 3 and NaNO 3 . Figure 7 shows a typical spectrum for a KNO 3 /KM nO 4 particle. Four overtones can be identi ed at 1736 (2n 1 ), 2591 (3n 1 ), 3433 (4n 1 ), and 4279 (5n 1 ) cm 2 1 in addition to n 1 at 891 cm 2 1 . ...

We report the influence of the nanosized effect on the optical properties of non-centrosymmetric ZnO nanoparticles. In this study confocal Raman scattering was employed to investigate the strain effect of the softening A1(LO) phonon mode while controlling particle sizes from 55 � 1 to 32 � 1 nm. The observations reveal a positive Poisson ratio betw...

This work aims at the impact of the electrostatic interaction between analyte molecules and silver nanoparticles (Ag NPs) on the surface enhanced Raman scattering (SERS) performance. For this, we fabricated nanostructured plasmonic films by immobilization of Ag NPs on glass plates and functionalized them by a set of differently charged hydrophilic...

Single crystals of 0.75(Na0.5Bi0.5)TiO3-0.25(Sr0.7Ca0.3)TiO3 (NBT-25SCT) were grown by top seeded solid state crystal growth. X-ray diffraction of a polycrystalline ceramic sample and Raman scattering of a single crystal reveal that rhombohedral symmetry is predominant in the structure. The relative permittivity curves of (001), (110) and (111)-ori...

CdO/CdS/textured-ZnO/ZnO heterostructure was synthesized using a combination of electrochemical etching and chemical deposition methods. Electrochemical etching was used to form a textured ZnO layer. Chemical deposition of a solution containing CdCl2 was performed to prepare a CdS film with CdO nanoparticles on the surface. The obtained nanocomposi...

In this paper, we have investigated the main properties of the Raman and fluorescent matrix of scattering by microspheres using the matrix scattering formalism. The coherent and incoherent inelastic scattering of incident light by a microsphere is described by the Stokes parameters. We demonstrate the main symmetry properties of the coherent and incoherent Raman and fluorescent scattering matrices. Numerical results are presented to illustrate the Raman scattering efficiency, cross-phase coefficient, and some other parameters of scattering by microspheres.
