We present our recent results on the development and characterization of hybrid sytems consisting of plasmonic nanostructures and organic dye molecules in a J-aggregate state. The measured spectra exhibit a strongly suppressed signal at wavelengths which correspond to the J-aggregate band, which is indicative of strong interaction between the plasm...

... with the changes in the absorption spectrum we also observed some changes in luminescence properties of hybrid J-aggregates/gold nanorods complexes. Figure 3 shows the photoluminescence spectra of plasmon-exciton systems formed from gold nanorods of three different sizes and J-aggregates. For the resonant conditions when absorption band of gold nanorods centered at the same wavelength as absorption band of J-aggregates (Fig. 1), photoluminescence spectrum of the hybrid system shows two pronounced peaks (Fig. 3b, upper curve). ...

For the resonant conditions when absorption band of gold nanorods centered at the same wavelength as absorption band of J-aggregates (Fig. 1), photoluminescence spectrum of the hybrid system shows two pronounced peaks (Fig. 3b, upper curve). Spectral positions of these two bands are very close to the ...

... of two resonances in absorption spectrum of the hybrid structure (Fig. 3). However, for the hybrid systems with higher detunings (red and blue curves in Fig. 1 and Fig. 2) spectral positions of PL bands strongly deviate from the positions of the peaks in absorption spectra (red and blue curves in Fig. 1 and Fig. 2). At the present this phenomenon is under close investigation. One of the reasons for such a ...

Plasmon-mediated energy transfer is highly desirable in photo-electronic nanodevices, but the direct injection efficiency of "hot electrons" in plasmonic photo-detectors and plasmon-sensitized solar cells (plasmon-SSCs) is poor. On another front, Fano resonance induced by strong plasmon-exciton coupling provides an efficient channel of coherent ene...
