We report the phototransferred thermoluminescence of tanzanite induced by 470 nm blue light. A glow curve measured after irradiation to 120 Gy and heating at 1 °C s⁻¹ shows three nominal peaks at 86 °C (peak I) and two secondary peaks at 160 °C and 320 °C. The latter two peaks are collocated peaks with each one consisting of multiple components. Phototransferred thermoluminescence is only reproduced at peak I. Although this work addresses phototransfer, the system studied is unconventional in that the phototransferred TL is associated with an indeterminate number of donors. A matrix-based method has been used to analyse the time-response profiles of the phototransferred thermoluminescence. Competition effects, where putative donor electron traps act in competition with acceptor electron traps, have been studied using empirical models.

我们报告了由470 nm蓝光诱导的坦桑石的光转移热致发光。辐射至120 Gy并在1°C s ^-1加热后测得的辉光曲线显示了在86°C（峰值I）的三个标称峰和在160°C和320°C的两个次级峰。后两个峰是并置的峰，每个峰都由多个成分组成。光传递的热致发光仅在峰I处再现。尽管这项工作解决了光传递问题，但是所研究的系统非常规，因为光传递的TL与不确定数目的供体相关。基于矩阵的方法已用于分析光传输热致发光的时间响应曲线。已经使用经验模型研究了竞争效应，其中假定的供体电子陷阱与受体电子陷阱竞争。
