摘要：

LiNbO3 (LN) crystals possess useful optical properties, which are strongly dependent on both the crystal stoichiometry and the content of dopants such as Mg2+, Zn2+, In3+, and Sc3+. Such elements drastically reduce photorefraction at a sufficiently high threshold concentration, which for Zn is in the range of 7–8 at. % and was supposed to be connected with the change of dopant-atom localisation in the lattice. We report the results of a single-crystal neutron study of stoichiometric, congruent, and doped (with 8.2 at. % Zn) LiNbO3 at T=78 K and 298 K and also a multi-pattern powder neutron and X-ray Rietveld refinement of the doped material. Zn ions occupy both Li and Nb sites and there is no residual Nb on Li sites. LN single crystals are very perfect, and extinction problems are discussed.
