Short-wave UV luminescence of BaF2 crystals caused by crossover transitions
Valbis Ya. A., Rachko Z. A., Yansons Ya. L.
The spectrum of the intrinsic luminescence of BaF2 crystals has been measured over the range 3.5-10 eV. Four short-wave emission bands that are observed are linked to crossover transitions from the 2p¥~ upper valence band to the 5/?Ba2+ cation band.
