Abstract The deconvolution of thermoluminescence (TL) glow curves into a sum of individual peaks described by First Order Kinetic (FOK) equations, implies that retrapping probability should be negligible compared with recombination during the readout (to avoid non-linearity) but not during irradiation (to allow the filling of the traps with the produced electron-hole pairs). In this contribution, some examples of TL glow curves simulated using a general model are discussed to show that FOK shape and deconvolution into individual glow peaks fitted by FOK equations is compatible with a non-negligible traps filling process during irradiation with the appropriate choice of kinetic parameters and probability factors.

热释光材料辐照和加热过程的数值分析

摘要 热释光 (TL) 辉光曲线解卷积为由一阶动力学 (FOK) 方程描述的单个峰的总和,这意味着与读出期间的重组(以避免非线性)而不是辐照期间的重组相比,重捕概率应该可以忽略不计(允许用产生的电子-空穴对填充陷阱)。In this contribution, some examples of TL glow curves simulated using a general model are discussed to show that FOK shape and deconvolution into individual glow peaks fitted by FOK equations is compatible with a non-negligible traps filling process during irradiation with the appropriate choice of kinetic参数和概率因子。
