摘　　要： 通过１－乙酰乙酰基－３－甲基吲哚（Ｉ３ＭＫ）与各种稀土离子在７７Ｋ乙醇刚性溶液体系中的荧光光谱、磷光光谱的测定，进行了Ｉ３ＭＫ向稀土离子能量传递过程的静态分析；从Ｉ３ＭＫ和Ｉ３ＭＫ－Ｔｂ（Ⅲ）体系的荧光寿命、磷光寿命、量子产率，时间分辨光谱等，计算了各主要能量传递过程的速率常数和能量传递效率，进行了该体系能量传递过程的动态分析，提出了Ｐｅｒｒｉｎ公式的修正参数，讨论了Ｉ３ＭＫ－Ｔｂ（Ⅲ）体系的能量传递机理． The energy trasfer process of I3MK-RE(Ⅲ)(I3MK=1-acetoacetyl-3-methylindole)complex system in alcohol solution at 77K was analysed with the static properties such as fluorescence and phosphorescence spectra. The rate constant and the efficiency of main energy trasfer process were calculated from fluorescence lifetime, phosphorescence lifetime,quantum yield and time-resolved spectra of I3MK and I3MK-Tb(Ⅲ)stsyem.Accordingly,the dynamics of the energy-transfer process in this system was analysed.A modification of the perrin formula was proposed and the mechanism of the energy transfer of the complex system was disscussed.
