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。
Reported that Cu +, Eu2 + co-activated Ca1-a. Luminescence properties of Mg.S, changes of matrix composition and the relationship between the fluorescence properties. The emission spectra of Cu + and Eu2 + in pure CaS matrix are located at 430nm and 630nm, respectively. With the increase of Mg content in the matrix, the emission peak wavelengths of red and blue regions are basically unchanged, but the intensity changes obviously. When n is 0.25 When the red zone launched the strongest intensity.
