摘要
采用化学沉淀法制备了Sr4Al14O25:Eu2+,Dy3+蓝绿色长余辉发光粉。通过XRD分析表明:经1100℃和1200℃煅烧制得的发光粉均为单一的Sr4Al14O25晶相,不含其它任何杂相,同时研究了硼酸的加入量对发光粉的物相变化和发射光谱的影响,通过场发射扫描电子显微镜分析了粉体的形貌和粒径。
Sr4Al14O25: Eu^2+ , Dy^3+ was prepared successfully by chemical precipitation method. The results of XRD analysis showed that the phosphor sintered at 1100℃ and 1200℃ was single phase without other phase. And the effect of H3BO3 on the emission spectrum and phase of phosphor was investigated. The particle morphology and size were analyzed via SEM.
