In some instances reported in the literature, a thermoluminescence peak that was expected to be excited by certain irradiation was not excitable at a certain temperature range below that of the peak although it was excitable at different temperature ranges. Two specific cases of this kind are calcium tungstate and semiconducting diamonds excited by UV light. The resemblance between these two different materials is quite surprising. In both cases, when the sample is UV irradiated at ~80 K and heated up, a glow curve consisting of two peaks is measured, one at ~150 K and the other at ~260 K. However, if the sample is held at temperatures between 150 and 260 K, the efficiency of excitation of the 260 K peak decreases very significantly with temperature so that it can hardly be excited above 200 K. In this work we present a possible energy-level model, previously used to explain the anomalous heating-rate effect, which can account for this rather anomalous effect. The model includes an electron trap, a hole trap and a hole recombination center. The transitions taking place during excitation, relaxation and heating are followed by using the appropriate sets of simultaneous differential equations. Simulation of the process by using a certain set of parameters is reported. Also, a theoretical account with approximations is utilized and both yield practically the same results. The effect of inability of excitation of the second peak at the temperature range between the two peaks is demonstrated.

在文献报道的某些情况下，预期被某些辐射激发的热释光峰在低于该峰的特定温度范围内是不可激发的，尽管它在不同的温度范围内是可激发的。这种类型的两种特殊情况是钨酸钙和由紫外光激发的半导体金刚石。这两种不同材料之间的相似性令人惊讶。在这两种情况下，当样品在~80 K 下接受紫外线照射并加热时，会测量出由两个峰组成的辉光曲线，一个在~150 K，另一个在~260 K。但是，如果样品保持在温度下在 150 到 260 K 之间，260 K 峰的激发效率随温度显着降低，因此在 200 K 以上很难激发。在这项工作中，我们提出了一个可能的能级模型，以前用于解释异常加热速率效应，这可以解释这种相当异常的效应。该模型包括一个电子陷阱、一个空穴陷阱和一个空穴复合中心。在激发、弛豫和加热过程中发生的转变之后使用适当的联立微分方程组。报告了使用一组特定参数对过程进行的模拟。此外，还使用了具有近似值的理论说明，并且两者都产生了几乎相同的结果。证明了在两个峰之间的温度范围内不能激发第二个峰的影响。在激发、弛豫和加热过程中发生的转变之后使用适当的联立微分方程组。报告了使用一组特定参数对过程进行的模拟。此外，还使用了具有近似值的理论说明，并且两者都产生了几乎相同的结果。证明了在两个峰之间的温度范围内不能激发第二个峰的影响。在激发、弛豫和加热过程中发生的转变之后使用适当的联立微分方程组。报告了使用一组特定参数对过程进行的模拟。此外，还使用了具有近似值的理论说明，并且两者都产生了几乎相同的结果。证明了在两个峰之间的温度范围内不能激发第二个峰的影响。
