Abstract :
The VUV luminescence properties of several Ba containing crystals in the temperature range of 10–300 K were investigated using energy- and time-resolved spectroscopy under excitation by XUV photons. The results are compared with those obtained under excitation by photons up to 40 eV. The revealed new emission bands can originate from the radiative recombination of valence electrons with the outermost Ba2+ 5p core holes and from the radiative transitions of multiply charged Ba ions. The possible inter-atomic cross-relaxation of holes from the fluorine to the barium ion in BaF2 was revealed as well.
