Abstract
In this paper, the phase equilibria of LiF-BaF2 and LiF-EuF3 systems under short-annealed and slow-cooled conditions have been explained. In these two systems, LiBaF3 and LiEuF4 exist as the line compounds in the respective systems under the present experimental conditions. The thermally stimulated luminescence (TSL) properties of EuF3 doped LiBaF3 compositions are investigated after irradiation with γ-ray. A typical glow peak at 390 K is observed in these samples, intensity of which increases up to 0.5 mol% of Eu3+ doping and then decreases due to concentration quenching. An intense glow peak at 540 K observed only in 1.0 mol% doped sample. Spectral studies of the TSL glows confirm Eu3+ ions as the luminescent centers.
