共沉淀法制备长余辉发光材料SrAl2O4:Eu2+,Dy3+的研究

Preparation of SrAl2O4: Eu2+,Dy3+ by the Coprecipitation Synthesis Technique

    摘要
  • 摘要: 用共沉淀 (CST)法制备长余辉发光材料SrAl2O4: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 1100℃。

     

    Abstract: The long afterglow materials,SrAl2O4:Eu2+,Dy3+ 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℃.
