Abstract SrAl2O4: Eu, Dy, B particles were added in a phosphate glass (90NaPO3-10NaF (in mol%)) using the direct doping method. For the first time, the composition of the particles prior to and after embedding them in the glass was analysed using EPMA analysis. Boron was found to be incorporated in already distorted surroundings creating new trapping centers in the particles which are thought to be favourable for the tunnelling process and so for the afterglow at 10K. Despite the partial decomposition of the particles, the glass exhibit afterglow at low temperature confirming to be promising materials for low temperature applications.

来自 SrAl2O4 的低温余辉：含 Eu、Dy、B 的玻璃

摘要 SrAl2O4：使用直接掺杂法将Eu、Dy、B 颗粒加入磷酸盐玻璃（90NaPO3-10NaF（摩尔%））中。首次使用 EPMA 分析法分析了嵌入玻璃之前和之后的颗粒组成。发现硼被掺入已经扭曲的环境中，在粒子中产生新的俘获中心，这被认为有利于隧道过程，因此有利于 10K 的余辉。尽管颗粒会部分分解，但玻璃在低温下仍会显示余辉，这证实是用于低温应用的有前途的材料。
