Abstract
Fluorescence spectra of Ce3+ ions in silicate, borate, and phosphate glasses melted in Ar were measured. The relative fluorescence intensity of Ce3+ in the ultraviolet region increased in the order of R = Ba, Ca, Sr, and Mg in the 20Li2O-20RO-60SiO2 glass samples and with decreasing BaO content in the BaO-B2O3 glass samples, respectively. In contrast, the relative fluorescence intensity of Ce3+ did not change with varying the glass composition in phosphate glass samples. The compositional dependence of the relative fluorescence intensity of Ce3+ is discussed in terms of redox reaction of Ce3+-Ce4+ in oxide glasses.
