| Abstract: | Groups of lines corresponding to octahedral cubic and trigonal impurity centers have been isolated in complex many-center luminescence and excitation spectra of Yb3+-doped KMgF3 and KZnF3 crystals. The crystal-field potentials derived from the spectra are in good agreement with those of similar centers in CsCaF3:Yb3+ crystal studied earlier. Fiz. Tverd.
