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.

Key words: energy band structure, partial density of states, total density of states, scintillators, lanthanides
