The research of properties of Eu~(3+)-doped cadmium aluminium silicate glass

摘要

We have prepared (40SiO_2-14Al_2O_3-(40-x) CdO-2Li_2O-2K_2O-2Na_2O -x Eu_2O_3) 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 Eu_2O_3, 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 Cd~(2+). 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 Eu~(3+).We can adjust and mix different intensity of light according to the demand.
