Compositional dependence of ultraviolet fluorescence intensity of Ce(3)(+)in silicate, borate, and phosphate glasses

Fluorescence spectra of Ce(3)(+)ions in silicate, borate, and phosphate glasses melted in Ar were measured. The relative fluorescence intensity of Ce(3)(+)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 conten...

Description
Summary:Fluorescence spectra of Ce(3)(+)ions in silicate, borate, and phosphate glasses melted in Ar were measured. The relative fluorescence intensity of Ce(3)(+)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 Ce(3)(+)did not change with varying the glass composition in phosphate glass samples. The compositional dependence of the relative fluorescence intensity of Ce(3)(+)is discussed in terms of redox reaction of Ce(3)(+)--Ce(4)(+)in oxide glasses.
