Trap distribution plays a crucial role in deciding the applicability of a material. The thermoluminescence (TL) parameter that describes trap distribution is η, which has never been discussed in TL analysis so far. TL analysis of a commercially available red persistent luminescent material (CaSrS:Eu) was performed using computerized glow curve deconvolution (CGCD) in the new general order kinetics. CGCD results showed that the red persistent luminescent material in the temperature range 300–600º K was comprised of nine peaks. Activation energy ranged from 0.66–1.27 eV. Frequency factor was in the range 10⁹ to 10¹¹ sec⁻¹. The major peaks of the red persistent luminescent material had lesser empty traps. The most important information provided by the analysis was that the major peaks of the red persistent luminescent material had 30–60% of the empty traps close to the filled traps, and this accounted for retrapping of thermally released electrons. This finding suggests that the occurrence of 30–60% empty traps close to the filled traps is a necessary requisite for a persistent luminescent material.

使用热致发光分析红色持续发光材料的陷阱分布。

陷阱分布在决定材料的适用性方面起着至关重要的作用。描述陷阱分布的热致发光（TL）参数是η，到目前为止，在TL分析中尚未讨论过。使用计算机辉光曲线去卷积（CGCD），以新的一般顺序动力学对市售红色持续发光材料（CaSrS：Eu）进行TL分析。CGCD结果表明，在300-600ºK温度范围内的红色持续发光材料由9个峰组成。活化能范围为0.66-1.27 eV。频率因子在10 ⁹到10 ¹¹ sec ^-1之间。红色持续发光材料的主峰具有较少的空陷阱。分析提供的最重要信息是，红色持久发光材料的主要峰中有30–60％的空陷阱接近于已填充的陷阱，这说明了热释放电子的重新陷阱。这一发现表明，在充满的陷阱附近出现30-60％的空陷阱是持久发光材料的必要条件。
