摘要: Optical spectroscopy and EPR are employed to study a β-PbF2 crystal doped with Yb3+ ions. The presence of only one paramagnetic center, the ion cubic symmetry, is established. Its optical lines identified, empirical system energy levels constructed, phenomenological field potential determined. information on phonon spectrum obtained from electron-vibrational structure absorption luminescence spectra.
