Abstract


The influence of gold nanoparticles in the high disperse silica matrix containing 0.004–0.06 wt.% of metal on the spectral behavior of adsorbed dye Rhodamine 6G is considered. Increasing the quantity of gold nanoparticles on the silica surface enhances the intensity of dye absorption spectra more than 2 times. The fluorescence enhancing of dye on the SiO2 surface containing 0.02 wt. % of metal was observed.
