Abstract

Series of Mg doped congruent LiNbO3 crystals were investigated by UV and IR spectrophotometry and AC conductivity. The position of the UV absorption edge, the shape of the absorption band of the OH- vibration and the value of the electrical conductivity at 400°C changed monotonously up to a critical concentration of Mg ions. Above the concentration of about 4.5×10-2 mol/mol Mg in the crystal anomalous behaviour was observed. We conclude that the mechanism of the incorporation of Mg ions changes at this concentration.
