Polycrystalline compounds of Rubidium Calcium Fluoride doped with samarium were synthesized by conventional high temperature solid state reaction method. Phase purity of the title compound was analyzed by PXRD study. The presence of functional groups has been identified by FTIR. The morphology of as-synthesized phosphor was analyzed by FE-SEM. Presence of metal ions was confirmed using EDAX study. The sharp PL emission was obtained at 599 nm under the excitations of 402 nm and 469 nm. The luminescence decay profile time was analysed. The Commission Internationale del’Eclairage (CIE) chromaticity coordinates of Sm³⁺ doped RbCaF₃ phosphor were found to be 0.495 and 0.483. The thermoluminescence property of X-ray irradiated RbCaF₃:0.6Sm³⁺ phosphor was analyzed by TL reader. The TL glow curve peak originated at 258° C. Order of kinetics, activation energy, symmetry factor and frequency factor were calculated by Chen’s method. X-ray-induced luminescence was recorded and corresponding dominant emission peak is 603 nm.
