摘要：
The photostimulated luminescence is studied for CsI-Tl crystal after irradiation with ultraviolet light in the 80-300K temperature range. The PSL creation spectrum coincides with the D absorption band at 80K. Three bands are observed in the stimulation spectra at 80K: 1400, 950 and 600 nm. The 1400 and 950 nm stimulation bands are presumably explained as optical transitions in the Tl-0 and Vk centres situated in the spatial correlated pairs. The stimulation at 600 nm band is ascribed to the unperturbed Tl-0 centres.
