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