摘　　要：本文以吖啶橙和罗丹明Ｂ作为能量转移中的给予体和接受体，分别探讨了不同阴离子表面活性剂对染料问能量转移影响。从染料分子所处微环境变化的角度阐明了分子聚集状态的变化是影响能量转移效率的重要因素。The energy transfer between Acridine Orange (AO) and Rhodamine B (RB) is studied and the effects of different anion surfactants are compared. It is found that most of the anion surfactants Which have been examined can enhance the energy transfer at very low dye concentration except.sodium octylsulfate. With sodium dodecyl benzene sulfonate AO RB as a typical System, the solution state of AO RB is discussed in details. The Experimental results indicate that surfactants can vary the distance between dye molecules, and the microcircumstence of molecular can affect the energy transfer efficiency greatly.
