Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

We presented the results of ab initio calculations of inorganic scintillators BaF2:La3+ and BaF2:Lu3+ under pressure up to 5 GPa. The calculations were carried out in the framework of the density functional theory using Vienna Ab-Initio Simulation Package code. We evaluated the band gap and core valence band of BaF2 crystals activated by La3+ and Lu3+ ions, and we considered the possibility of using the materials as scintillators.
