dc.description.abstractA series of Gd3+ doped NaBaBO3 phosphors were synthesized via a combustion approach. The TL data collected by means of a combination of a commercial SCHOTT BG39 and HC414/46 filters was studied to evaluate basic kinetic parameters. Tm-Tstop and, various heating rate (VHR) and computerized glow-curve deconvolution analyses were utilized to analyze collected data. Our findings indicate that luminescence process in scrutinized material may obey first-order kinetics because no shift in the experimental TL glow curves with increased dose was observed. The TL dose response of the TL glow peaks exhibited a linear characteristic up to 20 Gy. The Tm-Tstop method revealed that the number of the component TL glow peaks in the complex glow curve with and without preheating process consisted of six well-isolated and three overlapping glow peaks, respectively. The number of peaks obtained by deconvolution was perfectly matched with those obtained by Tm-Tstop and the figure of merit (FOM) values with and without preheating were 0.84% and 1.48%, respectively. The activation energy value found for the peak at 312 °C using the various heating rate (VHR) method was very close to those of deconvolution method. The total loss of response of TL glow curve sensitivity was much less (only ± 2%) after 10 cycles of reuse. © 2021 Elsevier B.V.
