Energy band structure of LaF3:Sm and LaF3:Pm crystals

Abstract

The papers presents the results of the theoretical calculations of the partial and total density of states of LaF 3 :Sm and LaF 3 :Pm crystals. We analyze the positions of 4 f and 5 d energy states of activator ions in the energy structure of the host material. We calculated and described electronic energy band structures of the above mentioned crystals. We made a quantitative and qualitative comparison between the energy structure of LaF 3 :Sm and LaF 3 :Pm crystals.
