In this study, we developed Li3PO4-Al(PO3)(3) glasses doped with different concentrations (0, 0.1, 0.2, 0.5 and 1.0%) of Ce and studied the optical, scintillation and dosimeter properties. The scintillation and photoluminescence (PL) emissions showed an intense emission due to the 5d-4f transitions of Ce3+. In addition, the scintillation and PL decay times of Ce3+ were obtained for 25-32 and 26-29 ns, respectively. These results were typical for Ce-doped scintillator. Moreover, as a dosimeter property, 0, 0.1, 0.5 and 1.0% Ce-doped glass samples showed thermally stimulated luminescence (TSL) around 150-200 and 350-400 degrees C with a good liner response over 0.5-10 Gy.
