The lattice site of Er has been determined in LiNbO3:Mg,Er crystals by the Rutherford backscat tering channeling technique. It has been shown unambiguously that Er occupies Li site in the crystal lattice. OH- absorption band has not been found in the 3500–3525 cm1 region. The RBS result confirms the assumption that OH- ions may form defect complexes only with those trivalent impurities which replace niobium.
