Paper Abstract

The Tb:Fe:LiNbO3 and LiNbO3 crystals with vary Li/Nb ratio in the melt were grown by the top-seed solution growth (TSSG) method and Czochralski technique, respectively. Their Li/Nb ratios were calculated by the lattice parameters. The defect structure of the Tb:Fe:LiNbO3 and LiNbO3 with vary Li/Nb ratio in the melt crystals was studied by X-ray analyses and UV spectra. The results show that an increase of Li/Nb ratio in the melts leads to a decrease of the lattice constants, which is accompanied by an improvement of the LiNbO3 lattice structure because of diminishing concentration of intrinsic nonstoichiometric defects.
