Abstracts

EN

Thermoluminescence of CaF_{2}:Ce, BaF_{2}, and BaF_{2}:Ce irradiated at room temperature is reported. X-ray induced emission spectra of the samples show that both excitonic (due to e^{-}+V_{K} recombination) and Ce^{3+} d-f luminescence may contribute to thermoluminescence signal. The simple Randall-Wilkins model 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.
