The low temperature 4f13-4f125d absorption and emission band shapes of the impurity Tm2+ ions have been simulated within adiabatic approximation on the basis of a microscopic model operating with the real phonon spectrum of the host CaF2 lattice. Crystal field parameters and electron-phonon coupling constants were treated in the framework of the exchange charge model. Results of simulations of the spectral envelopes agree satisfactorily with the experimental data available from literature.
