Excitation and emission spectra of Mn 2+ ions in calcium fluoride have been studied using the photoluminescence technique. An analysis of the positions of the Mn 2+ crystal‐field transitions with aid of the model developed by Curie et al. was performed to determine the relevant crystal‐field parameters and the covalency parameters f _ s and f p of the Mn 2+ ions entering substitutionally for Ca 2+ ions in an O h symmetry cubic environment. The A s isotropic and A p anisotropic superhyperfine coupling constants of Mn 2+ in CaF 2 are also calculated and compared with those previously measured through the use of EPR technique.
