Sn-doped 50BaO–50P2O5 glasses were synthesized by the melt-quenching method, and their radiation response properties were evaluated. In both photoluminescence (PL) and scintillation, all the samples showed broad emission peaks at around 450 nm owing to the T1–S0 transition of Sn2+. Among the samples, the highest PL quantum yield (31.3%) and light yield (240 ph/5.5 MeV-α) were obtained in the 1% Sn-doped sample.
