“…The new expressions were originally deduced by Kitis and Vlachos [25] to fit the glow-peaks generated with 1 R < and 1 R > , where / n m R A A = is the trappingrecombination coefficients ratio. The accuracy of these equations in calculating the activation energy was verified for the glow-peaks simulated by different TL models [24,26,27].…”

The kinetic parameters of the glow‐peaks of Harshaw – LiF:Mg, Ti (TLD) and Poland – LiF:Mg,Ti (MTS) dosimeters were investigated at different dose levels using the computerized glow‐curve deconvolution (CGCD) algorithm. The results showed that the glow‐curve structure and the kinetic parameters of the MTS – 6 and the TLD dosimeter are identical. In addition, the glow‐curve structure and the kinetic parameters of the MTS – N and MTS – 7 dosimeters. However, unusual low activation energy (∼1.67 eV) and frequency factor (∼1015 s–1) values were detected for peak 5 of MTS – N, and MTS – 7 at the 50 Gy dose‐level. Moreover, unlike the activation energy and the frequency factor of peak 5 of the TLD dosimeters, the activation energy and the frequency factor of peak 5 of MTS – N and MTS – 7 are substantially dependent on the absorbed dose level. The results also showed that peak 2 of the same dosimeters has also unusual low activation energy and frequency factor values. However, these values showed high stability over the different dose levels. The explanations of these unusual behaviors of peak 5 were discussed and a correlation between peak 2 and peak 5 was pointed out.

“…Furthermore, all analytical peak model expressions fail to describe the glow-peak in the cases in which the re-trapping probability becomes greater than the recombination probability ( ), and the sample absorbed dose is in the saturation range ( ). Kitis and Vlachos (2013) deduced general semi-analytical expressions based on the OTOR to describe a single thermoluminescence (TL) glow-peak. The advantages of these expressions that they can accurately describe the TL glowpeaks even in the cases in which the other TL expressions were failed (Sadek et al, 2014A).…”

“…Another drastic approach has recently been suggested for general semianalytical expressions for TL, OSL, and other luminescence stimulation modes derived from the OTOR model using the Lambert W-function [10]. This function has some advantages, especially when the retrapping probability becomes greater than the recombination probability, which remains a problem of all analytical peak model expressions.…”

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 ± 0.11, eV, 1.23 ± 0.05 eV, and 1.11 ± 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.
