The electronic structures of LiBaF 3 crystals containing F-type color centers are studied in
the framework of the fully relativistic self-consistent Direc–Slater theory, using a numerically …

The most possible substituting positions of impurity magnesium ions in LiBaF 3 crystal are
studied using the general utility lattice program (GULP). The electronic structures of Mg-doped …

The positions of the interstitial fluoride atoms in LiBaF 3 crystal are simulated by GULP. It is
found that the formation energy is low when interstitial fluoride atoms at the center of the …

The most likely substituting positions of impurity oxygen ions in LiBaF{sub 3} crystals are
studied using the general utility lattice program (GULP). The calculated results indicate that the …
