共沉淀法制备长余辉发光材料SrAl_2O_4:Eu^(2+),Dy^(3+)的研究

Preparation of SrAl_2O_4: Eu^(2+) ,Dy^( 3+) by the Coprecipitation Synthesis Technique

用共沉淀 (CST)法制备长余辉发光材料SrAl2 O4 :Eu2 + ,Dy3+ (SED) ,用红外光谱仪 (IR)、X射线粉晶衍射仪 (XRD)、荧光光度计对制备产物进行分析测试 ,确定了用共沉淀法制备SED长余辉体的最佳条件 ,其最佳灼烧温度为 110

The long afterglow materials,SrAl 2O 4:Eu 2+ ,Dy 3+ prepared by the CST is test on the IR,XRD and luminescents of phospher.The excellent synthesis conditions are determined,and the optimum sintering temperature is 1100℃.
