- Abstract
- The effect of cerium concentration and the addition of Sb2O3 on the light emission of cerium-contained glass were investigated. The glass matrix composition was 20Y(2)O(3)-25Al(2)O(3)-55SiO(2), the CeO2 concentration ranged from 0.05 to 0.5 mol%, and Sb2O3 was added at concentrations of 0.02 to 0.1 mol%. The Ce3+ and Ce4+ absorption bands were observed at approximately 330 nm and 240 nm, respectively. A broad emission band at 400 nm, due to the 4f-5d transition of the Ce3+ ion, was observed under illumination by a UV light at 330 nm. The photoluminescence intensity of Ce3+ had a maximum value at a CeO2 concentration of 0.1 mol%. Adding Sb2O3 decreased the Ce4+ absorption intensity and enhanced the light emission intensity of Ce3+ by about 45%.
