Paper Abstract

The influence of growth defects on optical properties of Lill crystals in exciton region is considered. Lithium hydride crystals consist of ions having S2, S2 electronic configuration. Therefore, LiH belonging to the NaC1 crystal modification differs from typical alkali-halids compounds with p6, p6 symmetry of an electronic subsystem. The densely stacked forecentered anion sublattice with S2-valent electrons forms a wide (about 6 eV) valent zone and determines the behaviour of electronic excitation in LiH. The bottom of the transmission zone is formed by p6-states of lithium ions. The conversion of S and p electron valent levels is affected by S-valent states of hydrogen ions.
