用Langmuir-Blodgett(LB)膜方法组装了可发红色荧光的钐配合物有序分子膜。用时间分辨技术得到了其激光诱导荧光光谱，并分析了荧光光谱的精细结构，计算了有序分子膜中钐离子的能级常数，测定了配合物中心离子的荧光寿命，从分子内及分子间能量转移机理上研究了分子存在状态、膜中组分对钐配合物荧光寿命及能级常数的影响。

Organized molecular film of a samarium complex was assembled by using Langmuir-Blodgett (LB) film method. The laser induced fluorescence spectra were recorded with the time-resolved technique. The fine structure related to radiative transition of Sm(III) was observed. The fluorescence lifetime as well as the energy level constant of Sm(III) in the LB film was calculated. Some factors influencing the fluorescence emission were investigated by considering the existing states and components in LB films.

Key words: SAMARIUM COMPLEX, L-B MEMBRANE, FLUOROSPECTROPHOTOMETRY, FLUORESCENT LIFETIME
