Abstract
Scintillation and dosimetric properties of 6LiF-CaF2 eutectic composites doped with different concentrations of Ce (0, 0.1 and 0.5%) were investigated. The Ce-doped samples showed scintillation due to the 5â¯d-4f transitions of Ce3+ and self-trapped excitons (STE) at 320-340 and 300â¯nm, respectively. Furthermore, the Ce-doped samples exhibited thermally-stimulated luminescence (TSL) with glow peaks around 150â¯Â°C after X-ray irradiation of 1000â¯mGy. The TSL response of the 0.5% Ce-doped sample increased monotonically with X-ray dose over a dose range of 0.1-1000â¯mGy. Moreover, the Ce-doped samples showed optically-stimulated luminescence (OSL) with peaks at 320-340â¯nm due to the 5â¯d-4f transitions of Ce3+ under 630â¯nm stimulation light after X-ray irradiation of 1000â¯mGy.
