Paper Abstract

Optical properties of supported silver nanoparticles with cyanine dyes overlayers were investigated. The spectrum of the hybrid material was treated as a result of mutual interactions between the plasmon oscillations in the metal nanoparticles and resonance absorption and refraction of dye molecules. The spectral positions of the plasmon resonances are shifted due to the anomalous refraction of dye molecules while the absorption of dye molecules is enhanced due to the incident field amplification in the near field of metal nanoparticles. The photoinduced transformations of hybrid material were also observed.
