Strontium aluminate long-afterglow luminescent ceramic and preparation method thereof
The invention provides a strontium aluminate long-afterglow luminescent ceramic and a preparation method thereof, the strontium aluminate long-afterglow luminescent ceramic has a rare earth element doped SrAlO structure, the highest afterglow luminescent intensity can reach 7000 mcd/m < 2 >, and the longest afterglow time can reach 30 h (gt); the preparation method comprises the following steps: weighing raw material powder, mixing, ball-milling, drying, sieving, calcining, forming and sintering to obtain the long-afterglow luminescent ceramic. The ceramic prepared by the technical scheme of the invention has green, blue and red long afterglow luminescence and certain jadeite luster, and can be used for auxiliary illumination, night indication, high-end decoration and other energy-saving and environment-friendly scenes, and the ceramic synthesis method is a solid-phase reaction method, is low in cost and simple to operate, and is suitable for large-size and large-batch industrial production.
本发明提供了一种铝酸锶长余辉发光陶瓷及其制备方法，结构为稀土元素掺杂的SrAlO结构，余辉发光强度最高可达7000mcd/m2，余辉时间最长可达30h(>0.32mcd/m2)，包括称取原料粉体，混合、球磨、烘干、过筛、煅烧、成型、烧结后得到长余辉发光陶瓷。本发明的技术方案制备陶瓷具有绿色、蓝色、红色长余辉发光，且具有一定的翡翠光泽，可以用作辅助照明、夜间指示、高端装饰等节能环保场景，陶瓷合成方法为固相反应法，成本低、操作简单，适合大尺寸、大批量工业化生产。
