摘要

研究了罗丹明6G (Rh6G)染料激光器作为供体和纳米粒子作为受体的杂化混合物中的能量传递。加入NPs后，Rh6G在蒸馏水中1×10-5M的吸收光谱强度增大。添加氧化铝Al2O3纳米粒子后，光谱明显改善。NPs的加入使Rh6G的荧光光谱因Förster共振能量转移(FRET)而猝灭。能量传递效率随着NPs浓度的增加而增加。在Rh6G/氧化镁MgO NPs中发现了能量转移效率的最佳值。在Rh6G/ Al2O3 NPs中存在较强的相关性。

The Effect of Mixing Nanoparticles on the Suspension Physical Stability

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.
