Thermoluminescence studies in KBr/sub x/I/sub 1-x/ mixed crystals

Thermoluminescence (TL) studies have been carried out in KBr, KI, and in different compositions of KBr/sub x/I/sub 1-x/ mixed crystals as a function of X-irradiation time. The TL glow peaks have been analysed and the trap depths and frequency factors have been calculated for different compositions. The complex TL peaks observed in these crystals were isolated by using thermal cleaning technique. The various glow peaks observed in these crystals were attributed to native impurities, first stage and second stage colour centers and the results have been discussed. (author)
