摘要

采用高温固相扩散法合成了La,0.96, Tb,0.01, Dy,0.03, BO,3,荧光粉，用X射线粉末衍射及光电子能谱法等研究了,γ,射线辐照对其发光性能的影响。氧化物中的Tb,3+,与Dy,3+,离子转变成硼酸盐形态后，其4d电子结合能发生变异，Tb,3+,、Dy,3+,离子4d电子结合能趋于一致。在1.5×10,4,Gy辐照时，La,0.96, Tb,0.01, Dy,0.03, BO,3,荧光粉的发光强度增至最大。,γ,射线辐照使La,0.96, Tb,0.01, Dy,0.03, BO,3,晶粒细化和Tb,3+,、Dy,3+,离子4d电子结合能峰面积改变，结合能峰面积的变化与辐照剂量对发光强度的影响结果是一致的。

Abstract

La,0.96,Tb,0.01,Dy,0.03,BO,3, luminophor is sythetized using high temperature solid phase. The luminescence of La,0.96,Tb,0.01,Dy,0.03,BO,3, by γ-ray irradiation was briefly studied. Tb,3+,、Dy,3+, 4d electron binding energy in La,0.96,Tb,0.01,Dy,0.03,BO,3, was close to 161.0eV. and Tb,3+,、Dy,3+, 4d binding energy peak areas changed with the change of irradiation doses. At 1.5×10,4,Gy dose, La,0.96,Tb,0.01,Dy,0.03,BO,3, has the maxim value of luminous intensity.
