Abstract: | Investigations of the OH− ion incorporation into LiNbO3 crystals and the comparison of calculated and measured densities show that undoped congruent lithium niobate crystals contain Li+ and O− − ion vavancies O and Li+. If really present, stacking faults are of inferior importance. The good agreement of the absorption edges of stoichiometric and of 2.7 mol% MgO containing congruent lithium niobate crystals is explained by the occupance of all oxygen sites within these crystals. |
