摘要
报道了Cu+、Eu2+共激活的Ca1-a.Mg.S的发光性质、基质组分变化与荧光性质的关系。Cu+和Eu2+在纯CaS基质中的发射光谱分别位于430nm及630nm附近,随着基质中Mg含量的增加,红、蓝区发射峰值波长基本不变,但强度发生明显改变,当n为0.25时,红区发射强度最强。
The fluorescence of Cu+ and Eu2+coactivated Ca1-'Mgn.S was reported. The emission bands ofCu+ and Eu2+peak at 430nm and 630nm in pure CaS host,respectively,with Mg composition rising inCa1~MgnS,the wavelengths of the red and blue emission bands are fixed. But that of the intensity willchange obvinusly. When n is equal to 0. 25,the intensity of the red emission band is the strongest.
