Fast Ce 3+ ‐activated borogermanate scintillating glasses with the density of 5.58–5.67 g/cm 3 were synthesized by melt quenching method in air atmosphere for the first time. The optical transmittance and X‐ray absorption near edge spectroscopy results confirm that Ce 4+ ions can be effectively reduced to Ce 3+ ions by adding 0.31 mol% Si 3 N 4 as a strong reducing agent during glass synthesis. The luminescence behavior under both ultraviolet and X ‐ray excitations indicate that the proposed Ce 3+ ‐activated borogermanate scintillating glasses have a broad emission band centered at 430 nm and a decay time of less than 25 ns. This will be of great interest in high‐energy physics and nuclear physics engineering.
