The photostimulated luminescence(PSL) of BaFCl:Eu2+ after ultraviolet irradiation is investigated. The photostimulation spectra after UV-irradiation are measured when we change irradiation temperature between 10 and 300 K. Meanwhile the dependence of PSL intensity of two kinds F-color centers on photostimulation temperature is studied, and the reasons which cause the difference of photostimulation spectra are analysed.
