摘 要:CaS∶Eu,Sm材料在光存储、光探测领域具有广阔应用前景,但制备过程中影响其发光性能的因素较多,彼此又有交互作用,不易获得最佳工艺参数。本文采用高温固相反应法,通过正交实验设计系统研究了灼烧温度、灼烧时间、稀土掺杂浓度、助溶剂用量对CaS:Eu,Sm发光性能影响的主次关系,经正交分析和验证实验确定了最佳工艺参数应为:Eu∶Sm∶Ca mol%=0.3∶0.3∶99.4%,1100℃灼烧0.5h,助熔剂LiF用量为7%。采用X射线粉末衍射仪、荧光分光光度计(耦合1064nm激光激励源)对样品的物相及发光性能进行了测试与表征。CaS:Eu,Sm has broad application prospects in the optical storage and light detection field.But it is very difficult to obtain the optimal preparation parameters because there are so many effect factors on the luminescence properties.In this paper,CaS∶Eu,Sm was prepared by the high-temperature solid-state reaction method,and the orthogonal experiments were adopted to studied the technological parameters,such as calcining temperature,calcining time,doping content,fluxing agent content,etc.The results show that the optimum condition is as following:Eu∶Sm∶Ca mol%=0.3∶0.3∶99.4%,calcined at 1100℃ for 0.5h with fluxing agent content of 6%.X-ray diffractometer and fluorescence spectrometer coupled with a 1064nm laser were used to test the phase and luminescence properties,respectively.
