The present study aimed at quantifying the relationship between TL and either CW-OSL or LM-OSL using commercially available magnesium oxide. The samples were bleached at two different temperatures, and a component-resolved analysis on the integrated signals was performed. According to the data of the present study, each one among the five observed LM-OSL component receives electrons from at least two different TL peaks. Two different fast OSL components were resolved in the LM-OSL curves, both accumulating electrons from all TL glow peaks with T_max>150°C. Component C ₃ is very well correlated with the TL peaks at 102, 135 and 194°C, while components C₄ and C ₅ are related to the TL glow peaks of 292°C, 353°C and 464°C. We note that for CW-OSL the resolution is good when two or more components differ in intensity by an order of magnitude. Blue stimulation depletes substantially the first two TL peaks but not the third peak. Substantial depletion of the high-temperature TL peaks is achieved only by using the LM-OSL configuration. The results of the present study suggest that the traps that contribute to TL and OSL are the same, despite using different recombination pathways.

商用氧化镁中热致发光与光致发光之间相关性的组分分辨分析

本研究旨在使用可商购的氧化镁对TL与CW-OSL或LM-OSL之间的关系进行量化。将样品在两个不同的温度下漂白，然后对积分信号进行成分分解分析。根据本研究的数据，在五个观测到的LM-OSL分量中的每个分量都从至少两个不同的TL峰接收电子。在LM-OSL曲线中解析出两个不同的快速OSL分量，它们都在T _max > 150°C时从所有TL辉光峰中累积电子。组分C ₃与在102、135和194°C时的TL峰具有很好的相关性，而组分C ₄和C ₅与292°C，353°C和464°C的TL辉光峰有关。我们注意到对于CW-OSL，当两个或多个分量的强度相差一个数量级时，分辨率很好。蓝色刺激基本上会耗尽前两个TL峰，但不会耗尽第三个峰。仅通过使用LM-OSL配置，即可实现高温TL峰的大量消耗。本研究的结果表明，尽管使用不同的重组途径，但促成TL和OSL的陷阱却是相同的。
