Sn-doped 30CaO–50B2O3–20SiO2 g lass samples were prepared by the conventional melt-quenching method, and the photoluminescence (PL), scintillation, and thermally stimulated luminescence (TSL) properties were investigated. The PL and scintillation spectra of the Sn-doped samples exhibited a broad luminescence band with a maximum at 410 nm due to a T1→S0 transition of Sn2+, and the PL and scintillation decay time constants were approximately 5.7 and 6.3 μs, respectively. The Sn-doped samples exhibited TSL glow peaks at ~80 and 280 °C after X-ray irradiation, and the TSL intensity increased monotonically with the X-ray irradiation dose from 10 to 10000 mGy.
