Thermoluminescence studies of CaSO 4 :Dy,P,Si phosphor under X-ray irradiation

Results of thermoluminescence studies on CaSO 4 :Dy,P phosphor with Si co-doping under X-ray irradiation are presented here. The peak emission temperature of the phosphor is found to be at 360 °C without any compromise in the intensity of emission when compared to commercially available standard phosphor CaSO 4 :Dy. The fading rate of the phosphor is around 2% over a period of 100 days.
