Time-Resolved Spectrum Detection System
The typical application of time-resolved spectroscopy is by measuring the fluorescence lifetime of atom and molecule radiation to obtain the excited state lifetime, transition probability, collision cross section, reaction speed, energy transfer and other relevant information.
This system is based on the time domain analysis system of the fluorescence lifetime testing application. It works by using pulse laser to excite samples to generate fluorescence radiation, then measuring the evolution relation of the fluorescence intensity over time. Usually the fluorescence lifetime is at nanosecond level, some phosphor and rare earth compounds samples have longer radiation lifetime is up to millisecond level.
