Description

The method of X-ray structural analysis is used to refine the nature of point defects observed in neodymiumdoped lanthanum oxosulfide samples obtained by stockbarger-Bridgman. The following types of point defects are found: vacancies in lanthanum, sulfur and oxygen sublattices, mutual settlement of oxygen and sulfur atoms in the anion positions, introduced atoms. These defects have a significant effect on coordinates of atoms, interatomic distances and lattice parameters
