N2 - We investigated the photoluminescence (PL), scintillation, and dosimetric properties of strontium aluminoborate glasses with different thulium (Tm) concentrations of 0.1, 0.5, 1.0, and 5.0%. The Tm-doped glasses were synthesized by the conventional melt-quenching technique. In the PL and scintillation spectra, the Tm-doped samples showed a sharp peak at 460 nm due to the 4f-4f (1D2→3F4) transitions of Tm3+. Among the samples tested, the 0.5% Tm-doped sample exhibited the highest intensity in PL and scintillation. In thermally stimulated luminescence (TSL), the Tm-doped samples showed a broad glow peak around 100 °C after X-ray irradiation of 10000 mGy. The 0.5% Tm-doped sample also showed the highest TSL intensity. Furthermore, the 0.1-1.0% Tm-doped samples exhibited a linear response against X-ray doses over a range of 10-1-104 mGy.
