【Abstract】 A detailed experimental set and theoretical analysis of the technique of pulse decay curve spectroscopy for fluorescence lifetime measurements are presented. It includes the construction of a nanosecond laser source, a changable PMT, a grating monochromator, a memory oscilloscope and a recorder.Fluorescence lifetimes of some compounds were measured and compared with the results of standard samples.更多还原
