Abstract

Basic fluorescence and radiation response properties of 7.5CeO 2-22.5CaO-20Al2O3-50B2O3 (in molar percent) glass were evaluated. The Ce-doped glass was prepared according to a conventional melt quenching method using a Pt crucible in air atmosphere. The photoluminescence (PL), thermoluminescence (TL), and optically stimulated luminescence (OSL) spectra showed a blue emission band due to the 5d-4f allowed transition of Ce3+. The fluorescence quantum efficiency and decay time of Ce3+ were estimated to be about 60% and 37ns, respectively. The glass exhibited good linear TL and OSL responses in 1-1000 and 30-3000 mGy dose ranges, respectively.
