文摘In the measurement of fluorescent lifetime based on time correlation-single photon counting technique by means of TAC, due to the contamination of multi-photons a deviation of fluorescent lifetime measured from the expected value is experimentally studied. A correction function instead of a simple exponential function is used to fit the experiment data. The validation of the correction function is checked using the experimental data of several test samples： YAP, NaI（T1） and LSO. The results show that the correction function well fits the data and the reasonable fluorescent lifetimes are obtained.
