Investigations of temperature dependence of the thermal shifts in Sm2+-doped SrFCl crystal

Temperature dependences of thermal shifts for all transitions in Sm2+-doped SrFCl crystal were investigated by using a full expression including both the static effect and the vibrational effect at temperature ranges 87 and 610 K. The Debye temperatures, the electron-phonon coupling parameters and the static parameters (A) for each electronic transitions are derived by fit the obtained analytical expression to experimental data. We have compared our results with experimental data, and our results were found to be satisfactor
