Scintillation and dosimetric properties of Ce-doped strontium aluminoborate glasses

Strontium aluminoborate glasses with different concentrations of Ce (0, 0.01, 0.05, 0.1 and 0.5 mol%) were synthesized by the conventional melt-quenching technique. After the synthesis, photoluminescence (PL), scintillation and dosimetric properties of the samples were evaluated systematically. In the photoluminescence and scintillation spectra, a sharp peak around 370 nm due to the 5d-4f transitions of Ce was observed. The 0.05% Ce-doped sample showed the highest intensity in PL and scintillation among the samples investigated. The 0.01-0.1% Ce-doped samples also showed thermally-stimulated luminescence (TSL) with a glow peak of around 90 °C after X-ray irradiation. The TSL response of 0.01-0.05% Ce-doped samples increased monotonically with X-ray dose over a dose range of 10− 1-104 mGy.
