In thermoluminescence (TL) models, the competition between energy levels for electron trapping is a direct consequence of conduction band mediation in electron transport. From a theoretical perspective, these competitive effects are considered responsible for many TL phenomena. Furthermore, while they are easily detectable in simulation studies, there are no clear and reliable criteria for their experimental verification. In the present work, it is suggested that in certain materials with narrow band gap energies, existing electron traps can be accessed by thermal stimulation up to 500 °C. It is possible to predict properties through simulation that can then be verified experimentally. The simulation is applied to a complex TL glow curve consisting of four electron trapping levels and one luminescence center. With the appropriate selection of simulation parameter values, the competition is limited solely to electron transport, rather than to significant differences in parameter values. The simulation indicated that the last peak serves as the primary competitor. Furthermore, the shape of the TL glow curve depends on the strength of the competition. When the competitor is strong, the lower temperature peaks behave as first-order peaks, and the shape of the glow curve remains stable as a function of dose. The last peak, which acts as the final competitor, exhibits behavior similar to that of the peak derived from the one trap, one recombination (OTOR) model. This OTOR-like behavior provides an excellent experimental test for the simulation results and, consequently, for the model used. The validity of the simulation was assessed by comparing the input values of kinetic parameters with the output values obtained from computerized glow curve deconvolution (CGCD) analysis for each TL glow curve.

模拟热释光剂量计中的峰特性，对所有电子阱进行电位刺激


在热释光 （TL） 模型中，电子俘获能级之间的竞争是电子传输中导带介导的直接结果。从理论角度来看，这些竞争效应被认为是许多 TL 现象的原因。此外，虽然它们在仿真研究中很容易检测到，但对其实验验证没有明确可靠的标准。在本工作中，建议在某些具有窄带隙能量的材料中，现有的电子陷阱可以通过高达 500 °C 的热刺激来接近。 可以通过模拟来预测特性，然后通过实验验证。该模拟应用于由四个电子俘获级和一个发光中心组成的复杂 TL 辉光曲线。通过适当选择仿真参数值，竞争仅限于电子传输，而不是参数值的显著差异。模拟表明，最后一个峰是主要竞争者。此外，TL 辉光曲线的形状取决于竞争对手的强度。当竞争者较强时，较低温度的峰表现为一级峰，辉光曲线的形状作为剂量的函数保持稳定。最后一个峰作为最终竞争峰，其行为类似于从“一个陷阱，一个复合”（OTOR） 模型得出的峰的行为。这种类似 OTOR 的行为为仿真结果提供了极好的实验测试，从而为所使用的模型提供了极好的实验测试。 通过将动力学参数的输入值与从每个 TL 辉光曲线的计算机化辉光曲线反卷积 （CGCD） 分析中获得的输出值进行比较来评估模拟的有效性。
