We have prepared (40SiO₂-14Al₂O₃-(40-x) CdO-2Li₂O-2K₂O-2Na₂O -x Eu₂O₃) cadmium aluminium silicate glasses doped with europium by high temperature solid-state reaction method. The absorption spectra, excitation spectra, emission spectra are obtained. With the increase of Eu₂O₃, the absorption peaks are founded increasing to the best doped concentration and then reducing, which is nonlinear relationship. The charge-transfer band is moved to 320 nm due to the addition of Cd²⁺. We can see that the ratio of peak in 591 nm and 615 nm is 0.6-0.75 in general, and is unrelated to doped concentration. By changing concentration of Eu³⁺.We can adjust and mix different intensity of light according to the demand.
