Abstract
Thermoluminescence of CaF2:Ce, BaF2, and BaF2:Ce irradiated at room tempera ture is reported. X-ray induced emission spectra of the samples show that b oth excitonic (due to e(-) + V-K recombination) and Ce3+ d-f luminescence m ay contribute to thermoluminescence signal. The simple Randall-Wilkins mode l is used to deconvolute glow curves into. seven to eight first-order peaks . Parameters of all traps are calculated and correlations between peaks in the curves of the examined materials are discussed.
