摘　　要：通过对SrAl2O4:Eu,Dy长余辉发光涂料进行发光学研究,得出涂料母体对SrAl2O4:Eu,Dy长余辉发光粉的发光不存在明显影响的结论,同时利用二级e指数衰减公式研究了长余辉发光涂料的发光动力学,并测得其快衰减寿命和慢衰减寿命的数值。By researching the luminescence of SrAl2O4：Eu,Dy long afterglow luminous paint, the conclusion was obtained that the influence of the coating matrix to SrAl2O4：Eu,Dy long afterglow luminous paint was not so obvious. Luminescence dynamics of long afterglow luminous paint was researched by using attenuation formula of second stages of E - index, and the value of quick attenuation lifetime and slow attenuation lifetime of long afterglow luminous paint were both measured.
