Abstract
Nowadays, thermoluminescence is a known phenomenon that is observed in many solids (insulators and semiconductors). Given the various applications, it is necessary to acquire accurate relationships that correctly describe this phenomenon. Meanwhile, the thermal quenching effect is one of the effective factors. This effect, is observed with both increasing temperature and the probability of non-radiative recombination. Also, by increasing the heating rate, the maximum temperature and maximum intensity of the thermoluminescence glow curve are affected,in a way that the maximum temperature increases, and the maximum intensity decrease. In this study, the variation of the thermoluminescence glow curve of CaF2: Mn(TLD-400)dosimeter has been investigated for different heating rates. This way, after observing the thermal quenching effect for this dosimeter, the related parameters were determined as W=3eV and C =2.1×1027 through the fitting of experimental data with the associated theoretical equation. The obtained thermal quenching parameters can be used for fitting the experimental thermoluminescence glow curves to the theoretical models to determine the kinetic parameters.
