Abstract: In the spectra of infrared absorption in the region of stretching vibrations of OH– -groups the effect is investigated of dopants Mg, Mg + Fe on the concentration of complex defects of MgNb – OH – MgLi, FeNb – OH – MgLi in lithium niobate crystals grown from the charge, synthesized with the use of homogeneously doped Nb2O5 precursor.
Keywords: homogeneous doping, charge, single crystal, lithium niobate, stretching vibrations of groups, complex defects.
