The thermoluminescent (TL) kinetics parameters of the perovskite-like KMgF3 activated by lutetium impurities

The aim of this paper is to conclude a long experimental work carried out over many years on the thermoluminescence (TL) characterization of a complex fluoride, i.e. the perovskite-like KMgF3 activated by different dopants. In the present case, KMgF3 was doped by Lu impurities in three different concentrations. The kinetics parameters, i.e. the activation energy, E, the frequency factor, s and the kinetics order were determined using the computerized glow curve deconvolution (CGCD). Because the presence of low-temperature peaks in the TL glow curve, a post-irradiation annealing was used to erase these peaks. After that, a new deconvolution was carried out and also the initial rise method was used for determining the activation energy of the main peak.
