摘要
稀土基荧光材料是由稀土离子和配体组成。单个稀土原子或多个稀土原子掺杂而成的稀土荧光基材料,在荧光色彩方面有让人瞩目的差异,单个配体或多个配体的稀土基荧光材料在结构、荧光性能等方面也有着不小的差别。这使得不少学者在该领域进行探索。本文首先介绍了稀土基荧光材料的发光机理,合成方法与影响因素。在有了初步了解之后,将稀土基荧光材料分为电荷转移发光、配体发光和稀土离子发光三大类,对其性能和机理进行综述。最后列举稀土基发光材料目前热门的应用,为稀土基荧光材料的研究做一定的参考。
Lanthanide-based fluorescent materials are composed of lanthanide ions and ligands. There are remarkable differences in the fluorescent colors of lanthanide fluorescent materials doped by a sin-gle or multiple lanthanide atoms. There are also significant differences in the structures and fluo-rescent performances doped by a single or multiple ligands. Therefore, this has driven many schol-ars to explore the field. In this paper, the luminescent mechanism, synthesis method and influenc-ing factors of lanthanide-based fluorescent materials are introduced. After preliminary under-standing, lanthanide-based fluorescent materials are divided into three categories: charge transfer luminescence, ligand luminescence and lanthanide ion luminescence, and their properties and mechanisms are reviewed. Finally, the popular applications of lanthanide-based luminescent mate-rials are listed, which can lay the foundation of the research for lanthanide-based luminescent ma-terials.
