摘要： 在不同的反应条件下,运用固相反应的方法合成了CaF2:Ce3+多种粉末磷光体,测定了它们的荧光光谱,发现了3种不同的发光中心,并探讨了3种发光中心的转化规律;研究了不同阳离子电荷补偿剂对CaF2:Ce3+光谱性质的影响;指出了不同发光中心的产生是电荷补偿途径不同所致。

关键词: CaF2, 发光中心, 磷光体, 铈离子, 电荷补偿

Abstract: A series of powder phosphors of CaF2:Ce3+ were prepared by solid state reaction. Three luminous centers were found and the fransformation among them has been examined. The effects of different cation charge-compensators on the spectral charactreristies of CaF2:Ce3+ have been investigated also. It showed that different luminous centers resulted from different charge compensating ways.

Key words: calcium fluoride, cerium ion, phosphor, luminous center, charge compensation
