We have investigated the scintillation and dosimeter properties of Sn-doped 40Li2O.40B2O3.20SiO2 glasses and the Sn-free glass. The emission peak in the photoluminescence spectrum appeared at 350 nm and the quantum yield of the Sn-doped glasses was 20-50%, monotonically increasing with Sn concentration. The photoluminescence decay constants of the Sn-doped glasses were characterised by fast (a few ns) and slow (5-6 μs) components while, for the Sn-free glass, only the fast component was apparent. For the scintillation spectra under x-ray irradiation, the peak emission wavelength in the photoluminescence spectrum was similar for both Sn-free and Sn-doped glasses, suggesting that the absorbed energy was dominantly transferred to the host emission. In thermally stimulated luminescence, glow peaks of all glasses were observed at 250-300°C. We have also confirmed that the thermally stimulated luminescence for all of the glasses exhibited a proportionality to x-ray dose.
