| 摘 要： | 以Sm~(3+)为激活剂,Na~+为电荷补偿剂,柠檬酸为配位剂,乙二醇作为辅助配位剂,采用溶胶-凝胶法合成前驱体,然后在800℃下焙烧,成功制备了一系列SrMoO_4∶Sm~(3+),Na~+红色荧光粉。用X射线衍射仪、扫描电镜、荧光光谱和傅里叶变换红外光谱等手段对样品的物相、形貌、组成、发光性能和量子效率等进行测试和表征。分析结果表明:制备的SrMoO_4∶Sm~(3+),Na~+荧光粉均为四方晶系结构,掺杂离子的加入对基质晶体结构影响不大。在403 nm近紫外光激发下,产物有4个发射峰,分别位于563、600、647和707 nm处,归属于~5G_(5/2)→~6HJ(J=5/2,7/2,9/2,11/2)的电子跃迁,其中位于647 nm处的主发射峰的相对发光强度最大。当Sm~(3+)的掺杂物质的量分数为1%~3%时,发光强度最好,当浓度超过1%~3%时,会发生荧光猝灭。对实验数据进行分析,确定荧光猝灭机理是由于钐离子间交换作用引起的,并计算了能量传递的临界距离为1.77~2.56 nm。此外,还详细研究了乙二醇对SrMoO_4∶Sm~(3+),Na~+荧光粉形貌的影响,研究结果表明:乙二醇加入量为5 m L时,产物形貌均匀,呈球形或椭球形;且分散性较好;荧光强度最大。
