Na2O-ZnO-TeO2-B2O3 (NZTB) glasses doped with Tm (0.1, 0.5, 1, and 2%) were synthesized by a conventional melt quenching technique, and their photoluminescence and scintillation properties were investigated. Some emission peaks due to the electronic transitions of Tm3+ appeared upon ultraviolet light and X-ray irradiation. Decay times were valid as the 4f–4f transitions of Tm3+. A 1% Tm-doped NZTB glass showed a full absorption peak under 241Am α-ray irradiation, and the light yield was estimated to be 51 photons/5.5 MeV-α when the peak channel was compared with a photoabsorption peak of 137Cs γ-rays measured with a Ce-doped Gd2SiO5 sample.
