Abstract

Abstract: A convenient and effective strategy of preparing the colorless and transparent Ce 3+ -doped aluminoborosilicate glass in air by high temperature melt-quenching method is revealed. It is easily achieved by the partial substitution of Si3 N4 for SiO2 within 20–25 mol%. The optimized Ce 3+ -doped aluminoborosilicate glass scintillaor ( y = 25%) is featured with a density of 4.6432 g/cm 3 and a lifetime of 35.36 ns, respectively. Compared to the glass without any substitution of Si3 N4 ( y = 0%), both the photo- and radio-luminescence intensity of the optimized Ce 3+ -doped aluminoborosilicate glass ( y = 25%) are enhanced by a factor of 11.05 and 10.58, respectively. The corresponding integrated raidoluminescence intensity is about 22.8% of that of BGO crystal irradiated by X-rays.
