本文用共沉淀法合成了钐掺杂的碱土金属硫酸盐发光体 ,研究了 γ—射线辐照前后其荧光性能 ,发现经 γ—射线辐照后 ,部分 S3+m 被还原为 S2 +m ,荧光光谱中出现 S3+m 、S2 +m 特征峰
In this paper, samarium-doped alkaline earth sulfates were synthesized by co-precipitation method. The fluorescence properties of γ-ray irradiated γ-ray were studied. It was found that part of S3 + m was reduced to S2 + m after γ- Fluorescence spectrum appears S3 + m, S2 + m characteristic peak
