1 Energy Transfer Efficiency of Silver Nanoparticles with Rhodamine 6G Dye
Absorption and Fluorescence spectra of the suspension of Ag nanoparticles with Rhodamine 6G (Rh6G) in distilled water, has been investigated for different amount of masses of Ag nanoparticles in dye solution. An absorption spectra enhancement were observed for different amount of masses, indicated that doping of Ag nanoparticles has a significant effect on the dye absorption spectra. Contrarily, all dye fluorescence emission spectra showed quenching as Ag nanoparticles amount of masses increased due to Förster resonance energy transfer (FRET).
