Deconvolution analysis of thermoluminescent glow curves in various commercial dosimeters using two different approaches in the framework of the one-trap, one-recombination model

This paper reports kinetic analysis on the thermoluminescence (TL) glow peaks of various widespread luminescence dosimeters. A common general order kinetic (GOK) approximation and a relatively recently suggested Lambert W-function equation were used. The activation energies and the order of kinetic parameters are the main subjects of the present study. According to the results of this study, the activation energies of the main dosimetric peaks are estimated as 2.05 $\pm $ 0.11, eV, 1.23 $\pm $ 0.05 eV, and 1.11 $\pm $ 0.06 eV for LiF based dosimeters (TLD100, TLD600, TLD700), Al$_{2}$O$_{3}$:C (TLD500), and BeO dosimeters, respectively. Moreover, a number of other peaks were deconvolved and investigated in terms of kinetic parameters and frequency factors. Additionally, the advantages of the Lambert equation, being completely analytical, are reported and compared to those of the GOK method while deconvolving TL glow curves. The results of this study suggest that the Lambert W-function is promising in revealing the physical meaning of trap-charge and recombination mechanisms for the characterization of materials throughout physical-based sciences.
