A highly effective method of synthesizing transparent and colorless Ce3+‐activated aluminoborosilicate glass in air by high temperature melt‐quenching is reported. This is achieved by partial substitution of AlN for Al2O3 without using any reduction in atmosphere. The optimized Ce3+‐activated aluminoborosilicate scintillating glass is featured with a density of ~4.5 g/cm3 and a lifetime of 41.74 ns. Compared to the glass synthesized without AlN substitution, both the photo and raidoluminescence intensity of the optimized Ce3+‐activated aluminoborosilicate scintillating glass are enhanced by a factor of 24.4 and 6.76, respectively. The corresponding integrated raidoluminescence intensity is about 17.6% of that of BGO crystal under X‐ray excitation at 30 kV and 3 mA, respectively.
