The ultimate goal of this work is the study of the effect of luminescence stimulations and signals reading modes combinations on the thermoluminescence intensity and glow curve behaviour for the same X-ray irradiation dose. Three interesting stimulating and reading modes are considered, namely, infrared stimulated luminescence (IRSL), blue light-emitting diode stimulated luminescence (BLSL) and thermally stimulated luminescence (TSL). The studied stimulation and reading modes combination protocols are (Protocol 1) IRSL-TSL, (Protocol 2) IRSL-BLSL-TSL and (Protocol 3) BLSL-IRSL-TSL. Experiments are performed on beryllium oxide (BeO) dosimeter. Results demonstrate well that the combination of reading modes have direct impact on the TL signal in terms of intensity and glow curve shape. It was also found that when reading modes are correctly combined, particularly when IRSL is applied first, then BLSL and TL, it is possible to collect two or more exploitable signals of different stimulation types for the same irradiation that can be used for different purposes and final applications.
这项工作的最终目标是研究发光激发和信号读取模式组合对相同 X 射线辐照剂量下热发光强度和发光曲线行为的影响。考虑了三种有趣的激发和读取模式，即红外受激发射发光（IRSL）、蓝光发光二极管受激发射发光（BLSL）和热受激发射发光（TSL）。所研究的激发和读取模式组合方案为（方案 1）IRSL-TSL、（方案 2）IRSL-BLSL-TSL 和（方案 3）BLSL-IRSL-TSL。实验在氧化铍（BeO）剂量计上进行。结果表明，读取模式的组合对 TL 信号的强度和发光曲线形状有直接影响。还发现，当正确组合读取模式时，特别是当首先应用 IRSL，然后是 BLSL 和 TL 时，有可能为相同的辐照收集两种或更多不同激发类型的可利用信号，这些信号可用于不同的目的和最终应用。
