这项研究提供了一个统一的介绍热释光（TL）辉光曲线反卷积的框架内的开源R包“tgcd”，根据各种分析表达式，描述第一，第二，一般，和混合级动力学以及最近发展的半解析表达式，来自一个陷阱一个重组中心（OTOR）使用Lambert W函数或Wright Omega函数的模型。我们提供了一个全面，灵活，方便，开放的程序来分析TL发光曲线，根据不同的模型和表达式。利用CaF2：Dy的热释光发光曲线对不同模型计算的动力学参数进行了一致性评价。计算机化的辉光曲线反卷积（CGCD）方法的性能也进行了测试，使用模拟的辉光曲线。结果表明，比较动力学参数确定从不同的模型表达式和那些使用实验TL评估方法，以评估反卷积结果的可靠性的好处。CGCD方法的准确性取决于所使用的模型表达式和TL材料的本征俘获参数。
This study provides a unified presentation of thermoluminescence (TL) glow-curve deconvolution within the framework of the open source R package “tgcd”, according to various analytical expressions that describe first-, second-, general-, and mixed-order kinetics as well as the recently developed semi-analytical expressions that derive from the one trap-one recombination center (OTOR) model that utilizes the Lambert W function or the Wright Omega function. We provide a comprehensive, flexible, convenient, and openly accessible program to analyze TL glow curves according to different models and expressions. The consistency of kinetic parameters determined using different model expressions was assessed using measured TL glow curve of CaF2:Dy. The performance of the computerized glow curve deconvolution (CGCD) method was also tested using simulated glow curves. Results revealed the benefits of comparing kinetic parameters determined from different model expressions and those obtained using experimental TL evaluation methods to assess the reliability of deconvo-.lution results. The accuracy of the CGCD method is dependent upon both the model expressions used and the intrinsic trapping parameters of the TL material.
