摘　　要：荧光寿命是一种特征于分子的光化学和光物理性质的光谱参数。本工作报道一种实验装置和技术可测定～20纳秒至数毫秒范围的荧光寿命,并对有机化合物、稀土螯合物、发光材料等不同类型样品的寿命数值大小与它们的分子结构、能级跃迁和光化学行为的关联作了讨论。The fluorescence lifetime is a kind of spectral parameter which is characteristic to the photochemical and photophysical properties of molecules. Owing to the necessity of requiring precise measuring technique, the reported data are ra-ther scanty.The present paper reports on an experimental setup which is capable of determining lifetimes ranging from 20 as to several miliseconds.The magnitude of lifetimes of various samples including organic molecules, rare earth complexes and luminescent materials have been correlated with their molecular structure and energy level transitions.
