Abstract

The features of the glow curves of LiF:Mg,Ti are dependent on many parameters of irradiation, storage, ionisation density and readout. These are presented herein with emphasis on their complexity. Successful applications require some understanding of the great diversity of the glow curves. Glow curve analysis/deconvolution in order to better understand the mechanisms is a 'tricky business' even with Tm-Tstop analysis. In the theoretical framework of spatially correlated trapping and luminescent centres, a mechanism is described which simulates the behaviour of composite peak 5 at different cooling rates and following photon bleaching at 3.65 eV.

LiF:Mg,Ti的热致发光辉光曲线：特性和机制。

LiF:Mg,Ti 辉光曲线的特征取决于辐照、存储、电离密度和读出等许多参数。本文将重点介绍其复杂性。成功的应用需要对辉光曲线的多样性有一定的了解。为了更好地理解其机制，辉光曲线分析/解旋是一项 "棘手的工作"，即使是氚-止振分析也不例外。在空间相关捕获和发光中心的理论框架中，描述了一种机制，它模拟了复合峰 5 在不同冷却速率和 3.65 eV 光子漂白之后的行为。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
