摘要：

We investigated scintillation and dosimeter properties of (LiF)-Li-6/CaF2 eutectic composites doped with different concentrations of Eu (0.005, 0.02, 0.1, 0.3, and 1.0). In the photoluminescence (PL) and scintillation spectra, an emission peak at 430 nm due to the 5d-4f transitions of Eu2+ was observed. The intensity of PL and scintillation for (LiF)-Li-6/CaF2:0.005%Eu was the highest among the samples tested. In thermally stimulated luminescence (TSL), several glow peaks of (LiF)-Li-6/CaF2:0.005%Eu were observed after X-ray irradiation of 1000 mGy. The TSL response exhibited a linear response against X-ray dose over a dose range of 1-10,000 mGy. In optically stimulated luminescence (OSL), an emission peak was observed at 430 nm during a stimulation by 630 nm light after X-ray irradiation of 1000 mGy. The OSL intensity was the highest for (LiF)-Li-6/CaF2:0.005%Eu among all the samples investigated.
