Paper Abstract

Optical properties of composite structures comprised of the island films of silver nanoparticles with a thin molecular layer of a dye rhodamine 6G were obtained and studied in this paper. In the near field of plasmonic nanoparticles enhancement and shifting of the maximums of the absorption and fluorescence spectra were observed. In the absorption and fluorescence spectra of thin molecular films with nanoparticles the new red-shifted band in comparison with spectra of thin films without nanoparticles was found. This band was associated with the formation of aggregates. Thus, the silver nanoparticles can contribute to fluorescence enhancement and formation of the aggregates in the rhodamine thin films.
