Popis:	LiMgF3:DyF3 phosphors were obtained as polycrystalline solids from the melting of component salts, with two DyF3 concentrations, 2.02% mol and 4.04% mol. In order to guarantee the homogeneity of the composition, the samples were crushed and the resulting powder was pressed to form pellet-shaped phosphors, some of which were sintered at 700 °C for 5 h, under atmospheric air. Thermoluminescence measurements of beta irradiated samples show that these phosphors exhibit adequate properties to be considered for development of thermoluminescence dosimeters. Integrated thermoluminescence as a function of dose displays a linear dependence with dose for doses below 20.0 Gy.
