Abstract During the past decade, our understanding of the nature of quantum tunneling processes in luminescence materials has been advanced significantly, by both experimental work and modeling insights into the underlying luminescence mechanism. This paper provides examples of analysis of thermoluminescence (TL) signals in feldspars, based on recent modeling work which showed that the shape of the TL glow curves remains practically unchanged after thermal and/or optical treatment of the samples. Analysis of the experimental TL glow curves in thermally or optically pretreated feldspars shows that these signals can be described as the sum of several Gaussian curves. While the positions and height of these Gaussians depend on the thermal and optical history of the sample, the width of the Gaussians apparently remains the same across the TL glow curve. TL glow curves are analyzed for 10 different samples, and the width of the Gaussian curves is found to be a common property characterizing all samples, at least within experimental error. Specifically it is found that the Gaussian width stays practically unchanged when the irradiated samples undergo thermal treatments for different times and temperatures, or alternatively when they undergo optical bleaching treatments with blue LEDs. The common overall shape of the TL glow curves has important implications for the use of these signals in thermochronometry.

长石中的量子隧穿过程：在热计时法中使用热释光信号

摘要 在过去的十年中，通过实验工作和对潜在发光机制的建模洞察，我们对发光材料中量子隧穿过程性质的理解得到了显着提高。本文提供了长石中热释光 (TL) 信号分析的示例，基于最近的建模工作，表明在对样品进行热和/或光学处理后，TL 辉光曲线的形状几乎保持不变。热或光学预处理长石的实验 TL 辉光曲线分析表明，这些信号可以描述为几个高斯曲线的总和。虽然这些高斯分布的位置和高度取决于样品的热历史和光学历史，在整个 TL 辉光曲线上，高斯分布的宽度显然保持不变。分析了 10 个不同样品的 TL 辉光曲线，发现高斯曲线的宽度是表征所有样品的共同属性，至少在实验误差范围内。具体而言，发现当辐照样品经历不同时间和温度的热处理时，或者当它们用蓝色 LED 进行光学漂白处理时，高斯宽度实际上保持不变。TL 辉光曲线的共同整体形状对于在热计时法中使用这些信号具有重要意义。具体而言，发现当辐照样品经历不同时间和温度的热处理时，或者当它们用蓝色 LED 进行光学漂白处理时，高斯宽度实际上保持不变。TL 辉光曲线的共同整体形状对于在热计时法中使用这些信号具有重要意义。具体而言，发现当辐照样品经历不同时间和温度的热处理时，或者当它们用蓝色 LED 进行光学漂白处理时，高斯宽度实际上保持不变。TL 辉光曲线的共同整体形状对于在热计时法中使用这些信号具有重要意义。
