Abstract

Energy transfer in a hybrid mixture of Rhodamine 6G (Rh6G) dye laser as a donor and nanoparticles (NPs) as an acceptor were studied. The absorption spectra of 1×10-5 M of Rh6G in distilled water showed an increase in peak intensity upon addition of NPs. Notably, the spectra were improved upon addition of Aluminum Oxide (Al2O3) NPs. The addition of NPs quenches the fluorescence spectra of Rh6G due to Förster resonance energy transfer (FRET). The efficiency of this energy transfer increases with an increasing concentration of NPs, and a best value of efficiency of energy transfer was found for the Rh6G/Magnesium Oxide (MgO) NP system. A similarly strong relationship was also found for for the Rh6G/Al2O3 NP system.
