| Abstract: | 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. |
