摘要：

Thermostimulated luminescence (TSL) phosphors based on CaSO4:Dy, Zn and CaSO4:Tm, Cd have been studied. These phosphors show an increase in the 220 degreesC TSL peak intensity by a factor of about 50% compared to CaSO4:Dy, as there is no change in the position of the peak temperature. Their dose response characteristics to Co-60 gamma radiation is similar to that of CaSO4:Dy. However, there are very minor changes in their photoluminescence intensity and excitation spectra compared with those of CaSO4:Dy.
