Individual bands of Mn2+ ion in the excitation spectra
of CaF2:Mn and CaAlF5:Mn have been identified
and the crystal-field parameters of these materials have been calculated.
Decrease of B and increase of Dq parameters for
CaAlF5 are associated with the increase of the covalence
degree of the Mn2+-F bond.
