Abstract

Near-stoichiometric Mn:Fe:LiNbO₃ crystals doped with various concentration of ZrO₂ were grown by top seed solution growth (TSSG) method in the air atmosphere. The Zr concentration in the crystal was determined by inductively coupled plasma optical emission spectrometer. The defect structures were analyzed by means of ultraviolet-visible and infrared transmittance spectra. The appearance of vibration peak at 3466 cm^-1 in infrared spectra manifested that Li/Nb ratio in crystals approached to stoichiometric proportion. The fundamental absorption edge represented continuous red-shift which was discrepancy with congruent doped LiNbO ₃ crystals showed that doping ions possessed different location mechanism. The light-induced scattering of the doped stoichiometric LiNbO ₃crystals were quantitatively scaled via incident exposure energy. The results demonstrated that Zr(2 mol%):Mn:Fe:LiNbO₃ crystal had the weakest light-induced scattering and the mechanism related to their defect structures was discussed.
