This study analysed thermoluminescence (TL) glow curves of the polymer pencil lead graphite (PPLG) due to its potential applications in radiation dosimetry. The TL glow curves provide information on the physical parameters of the defects participating in luminescence process. The glow curves for different diameters PPLG samples were obtained with varying temperature from 50 to 300 °C, at a fixed heating rate of 10 °Cs⁻¹. A number of methods (initial rise, peak shape and curve fitting) were used to fit the TL glow peaks of the PPLG samples obtained under photon dose of 200 Gy. From the fitted TL signals, the trap parameters such as the order of kinetics, the activation energy, the frequency factor, etc. for the individual peaks were numerically determined. The lifetimes of TL process were calculated assuming the first-order kinetics. The results are compared among the different methods adopted in this study. Implications about the possible results in glow curve deconvolution are discussed.

这项研究分析了聚合物铅笔铅石墨（PPLG）的热致发光（TL）辉光曲线，这是由于其在辐射剂量法中的潜在应用。TL辉光曲线提供有关参与发光过程的缺陷的物理参数的信息。在固定温度10°Cs ^-1下，在50至300°C的不同温度下获得了不同直径PPLG样品的辉光曲线。许多方法（初始上升，峰形状和曲线拟合）用于拟合在200 Gy光子剂量下获得的PPLG样品的TL辉光峰。从拟合的TL信号中，数值确定了各个峰的阱参数，例如动力学顺序，活化能，频率因子等。假设一阶动力学，计算TL过程的寿命。在本研究中采用的不同方法之间比较了结果。讨论了有关辉光曲线反卷积的可能结果的含义。
