摘　　要：采用高温固相法制备SrAl2O4：Eu^2＋，Dy^3＋长余辉发光材料。借助材料的激发光谱、发射光谱和X射线衍射，分析研究掺杂B对SrAl2O4：Eu^2＋，Dy^3＋发光材料发光性能的影响及合适的加入量。结果表明：B的加入量影响着发光材料的发光性质，B的最佳加入量为58％。The long afterglow luminescent material SrAl2O4：Eu^2＋,Dy^3＋ was prepared by high temperature solid-state method. Effects of doped B on the luminescent properties of phosphors SrAl2O4：Eu^2＋,Dy^3＋ were investigated by means of excitation spectra, emission spectra and X-ray diffraction spectra. As a result, the luminescence intensity was affected by the content of B as a flux.
