The dependence of photoluminescent of lithium niobate crystals of different composition and genesis in the near IR- region on stoichiometry, Zn concentration, doping method was observed. It was found that increasing in stoichiometry leaded to decreasing in the photoluminescence. At Zn = 6.5 mol. % in the LiNbO3 crystal an intense emission was observed at 1.45 eV with simultaneous quenching of the NbLi emission. Homogeneous doping method of LiNbO3:Mg,Zn crystal allowed to enhance the luminescence in the region of 1.3–1.5 eV relative to the crystals obtained by direct doping method of the melt.
