制备了一系列掺Ce3+的磷酸盐、硼酸盐、硅酸盐和锗酸盐玻璃，并对其光学性能进行了研究。透射光谱和光致发光光谱的实验观察表明，玻璃的光学碱度不同，会产生明显的散射效应。特别是，添加碱土氧化物作为玻璃网络原体的替代，由于极性较低的非桥接氧离子的数量增加，从而增加了系统的光学碱性，从而有助于激发和发射带的进一步红移。(c) 2006 Elsevier Ltd.版权所有。
A series of Ce3+-doped phosphate, borate, silicate and germanate glasses were prepared and their optical properties were investigated. Experimental observations on transmission and photoluminescence spectra show obvious Nephelauxetic effect depending on the optical basicity of glasses. Especially, addition of alkaline earth oxides as a substitution of glass network former contributes to the further red shifts of excitation and emission bands due to increases in the number of less polarized non-bridging oxygen ions which increase the optical basicity of the system.
