The aim of this study is to determine the thermoluminescence (TL) kinetic parameters of pure yttrium borate (YBO3) phosphor. The YBO3 phosphor synthesized by combustion reaction was converted into pellet form and TL measurements were made. The samples exposed to the beta dose in the range of 0.1-5 Gy were heated from room temperature to 500°C at a constant rate of 2°C/s. TL glow curves of the sample were obtained for both different doses and various heating rates. The current peak shape (PS), various heating rates (VHR) and glow curve deconvolution (GCD) methods were used to calculate the trap parameters of the TL dosimetric peak centered at 210°C by analyzing the obtained TL signals. When Chen's PS method was applied to TL peak displayed in different doses, the average activation energy (E) and frequency factor (s) were found to be 0.847 eV and in the order of 107 s-1. The E and s values obtained using two different VHR methods were 1.050 ± 0.05 eV and in the order of 109 ± 10³ s-1 for one and 0.890 eV and in the order of 108 s-1 for the other. The GCD method was applied using the 'tgcd' package of the R-studio program. As a result of applying deconvolution to the peak maximum obtained in beta doses of 0.5 and 5 Gy, two peaks matching the 1st order kinetics were obtained. The E values of the deconvolved peaks (peak 1) were found as 0.889 and 0.868 eV whereas the s values were in the order of 108 s-1. [ABSTRACT FROM AUTHOR]
