Abstract. We carried out preparation of homogeneously doped charge LiNbO3:Zn ([Zn] = 2,44 wt. %) of congruent composition (ratio [Li]/[Nb]=0,96). From this charge a LiNbO3:Zn (Zn ~ 2.12 wt. %) single crystal by the Czochralski method was grown. Defect complexes (VLi)–-OH– of the LiNbO3 cong and LiNbO3:Zn crystals were discovered by IR-absorption spectroscopy in the area of stretching vibrations of OH–-groups.
Keywords: homogeneous doping, charge, single crystal, lithium niobate, stretching vibrations of OH––groups.
