摘要
本文对吖啶橙-罗丹明6G-罗丹明B组合成各种混合染料体系的能量转移进行了研究。结果表明,在十二烷基硫酸钠的水溶液中,吖啶橙-罗丹明6G间,罗丹明6G-罗丹明B间、吖啶橙-罗丹明B间均能发生有效的能量转移。可以认为不仅染料单体,而且二聚体也是能量转移的有效形式;另外还从给予体的荧光量子效率与能量转移效率的竞争,探讨了表面活性剂对能量转移的影响。本文的工作将有助于拓宽能量转移的理论研究和应用范围。
The energy transfer among dyes-Acridine orange, Rhodamine 6G (R6G) and Rhodamine B (RB) is studied, and the effect of different surfactants is compared. It is found that in the aqueous solution of sodium lauryl sulfate the energy transfer from Acridine orange to R6G, from Acridine orange to RB, from R6G to RB can occur significantly even when the concentration of the dyes is very low. It is also found that not only the monomer but also the dimer are responsible for the energy transfer.
