稀土掺杂无机长余辉发光材料研究概况

摘要

主要介绍了长余辉材料的发展历史及其最近的发展概况;以及长余辉发光材料的主要分类,包括硫化物基长余辉发光材料,铝酸盐基长余辉发光材料和硅酸盐基长余辉发光材料等;并对长余辉材料发光机理的模型进行了比较详尽的探讨;同时根据长余辉材料的发展现状探讨了其研究方向和发展前景.%The history of the development of long afterglow materials,and a recent overview of the development are introduced.And the classification of the long afterglow phosphors is mainly including sulfide-based and aluminate-based long afterglow phosphors,as well as silicate-based.Furthermore,the models and mechanisms that have been suggested to explain the bright afterglow in various compounds are discussed.The research direction and the development prospects of the long afterglow materials are prospected.
