| 摘 要： | 文章借助于材料的发射光谱和结晶相组成分析研究了B2O3对Eu2+,Dy3+共激活铝酸锶发光材料发光性能的影响.B2O3在Eu2+,Dy3+共激活铝酸锶发光材料的合成过程中,一方面作为助熔剂,降低发光材料的合成温度;另一方面,硼酸盐的存在促进Eu3+离子转化为Eu2+离子的还原过程.但是,B2O3加入量的变化并不引起发光材料发射光谱峰值的变化.

| Abstract: | Effects of B 2O 3 on the luminescent properties of Eu 2+ ,Dy 3+ co activated strontium aluminate phosphors were investigated by means of emission spectra and X ray analysis.The addition of B 2O 3 reduces the synthesizing temperature as a flux,and promotes the reduction of Eu 3+ ions to Eu 2+ ions in the Eu 2+ ,Dy 3+ co activated strontium aluminate phosphors.However,the wavelengths of emission spectra peaks of phosphors do not change with the variation of B 2O 3 contents. |
