The Effect of Mixing Nanoparticles on the Suspension Physical Stability

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 1×10-5M of Rh6G in Distilled Water show increase in the intensity when adding NPs. noticeable, improve the spectra when adding Aluminum Oxide Al2O3 NPs. Adding NPs quench the fluorescence spectra of Rh6G due to Förster resonance energy transfer (FRET). The efficiency of energy transfer increase with increasing concentration of NPs. Best value of efficiency of energy transfer found in Rh6G/ Magnesium Oxide MgO NPs. Strong relationship was in Rh6G/ Al2O3 NPs.
