  • 摘要: 用微波高温固相法合成了Er3+单掺Lu2O3,Li+与Er3+共掺Lu2O3及Li+,Zn2+,Mg2+掺杂Lu2O3:Er3+的荧光粉。实验表明金属离子Li+、Zn2+、Mg2+、Er3+掺杂Lu2O3,不影响Lu2O3的立方晶相。扫描电子显微镜测量表明,Li+掺杂可以有效改善粉体的分散性和形貌,Li+,Zn2+,Mg2+共掺杂获得的粉体颗粒分布更加均匀,粒径范围为80~100 nm。379 nm激发下,Li+与Er3+共掺样品发光较单掺Er3+样品在565 nm处的发光增强了4.5倍,而Li+、Zn2+、Mg2+与Er3+共掺样品较其发光增强5.3倍。980 nm激发下,Li+与Er3+共掺样品,Li+、Zn2+、Mg2+与Er3+共掺样品的发光分别比单掺Er3+样品在565 nm处发光增强23倍与39倍,在662 nm处发光强度分别增强20倍与43倍。379 nm激发下,较单掺Er3+的样品,掺杂Li+的样品和Li+,Zn2+,Mg2+和Er3+共掺的样品荧光寿命均有所增加,而Zn2+、Er3+共掺及Mg2+、Er3+共掺样品的荧光寿命则有所缩短。
