Synthesis and Spectral Characteristics of RhB and Rh6G Dyes and their Mixture in Solid Matrix
The absorption and fluorescence spectra of RhB dye and Rh6G in solvent and doped in silica glass with different concentrations have been carried out in the spectral range of 450-750 nm. The fluorescence spectra have been recorded with two excitation wavelength 370 and 450 nm. CdS nanoparticles (NPs) were prepared by sol-gel method in order to investigate their optical behaviors as efficient Förster resonance energy transfer (FRET). Pure RhB and RhB dye doped in Silica glass with different concentrations were tested as acceptor from the CdS nanoparticles. In this paper, we study FRET behavior of CdS NPs with RhB dye and energy transfer between RhB dye and Rh6G dye.
