Abstract
Photoluminescence(PL) characterization is carried out on CsBr1-xClx:Euy2+ (x = 0.05, 0.1, 0.2, 0.3 y = 100 ppm, 200 ppm) crystals grown in vacuum with the Bridgman technique. PL studies show an increase in luminescence intensity with a decrease in bromide ion content. F(Br−) and F(Cl−) centers are formed due to γ-ray irradiation at room temperature. Photostimulated luminescence (PSL) emission is found to increase with an increase in irradiation dose from 7.5 Gy to 30 Gy at room temperature. From the results it is demonstrated that out of the different compositions studied, CsBr0.9Cl0.1:Eu2+ (200 ppm) phosphor has a linear PSL response with respect to irradiation dose.
