硼酸使掺铁铝酸锂发光增强的现象

Luminescence Enhancement Phenomenon of Fe^(3+)-doped Lithium Aluminate by Boric Acid

在硼酸存在下合成了掺铁铝酸锂荧光体,研究了在不同温度下硼酸加入量对荧光体发光强度的影响,并通过X射线粉末衍射和粒度分析,初步探讨了发光增加的原因。

LiAl_5O_8:Fe^(3+)phosphor was synthesized in presence of boric acid.In- fluence of added quantity of boric acid on luminescence intensity of the phosp- hors have been investigated at three di- fferent temperature and the reasons of luminescence enhancement were studied breliminarily by X-ray powder diffract- ion and sizing test.
