摘要
系统地分析和概括了稀土离子激活碱土铝酸盐体系长余辉发光材料的种类、特性、组成、结构、发光机理和制备技术,并根据长余辉发光材料研究现状,探讨了碱土铝酸盐长余辉发光材料的研究方向与发展前景。
Current research progress in alkaline earth aluminate-based persistent phosphorescent materials doped by rare earth ions are reviewed in this paper.The kinds and characteristics of the phosphorescent materials are summarized, their chemical compositions, crystal structures and their effects on luminescent properties are analyzed, and their luminescent mechanisms and synthesis methods are introduced and generalized,respectively.Based on present research and application status, the prospects of studies and applications of the alkaline earth aluminate-based phosphors are proposed.
