文摘

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.
