摘要
通过对掺Sr杂质的BaF2晶体进行辐照实验,研究BaF2晶体质子辐照的荧光谱特性,发现BaF2晶体质子辐照存在荧光增强效应,出现峰值为346nm锐峰。分析认为这与质子辐照引起的离子价态变化相关联,346nm荧光峰发射出自Sr2+离子。
The article reports the results of study of fluorescence spectra when proton irradiating BaF2： Sr crystals. It is showed that the fluorescence increasing phenomena of BaF2 crystals irradiated by proton and there is a sharp peak at 346nm to be observed. The results present that a valance state in BaF2 crystals can be changed during proton irradiation process and the 3d6nm peak comes from Sr2 ＋ fluorescence emission.
