摘要
设计组装了宽时域（１０－３ｓ～１０－９ｓ）和宽频域（激发波长几乎可以复盖３３７～８００ｎｍ波长）的激光光源分子荧光寿命测试系统。系统中配置了Ｎ２分子激光，Ｎｄ：ＹＡＧ激光及其泵浦的染料激光和美国ＥＧ＆Ｇ公司的４４００型信号检测和分析系统。通过对硫酸奎宁，荧蒽和稀土络合物典型样品的检测表明该仪器系统性能稳定，结果可靠。
A measurement system of broad time range (10-3 - 10-9s) and broad wavelength range (exciting wavelength almost covering 337-750 nm) was designed in order to get fluorescence lifetime of molecules. The system was mainly composed of N2 laser, Nd YAG laser or pumped pulsed dye laser, model 4400 signal detection and ana1ysis system (EG & G). The lifetime results of fluoranthene, quinin and rare earth complexes showed that the measurement system is reliab1e and efficient.
