Hydrogen in the from of OH- ions can be incorporated into LiNbO3 single crystals during the growth process. The infrared absorption band due to the OH- has been measured at room temperature. The OH- absorption peaks of pure and doped lithium niobate crystals have been investigated. It was found absorption peaks of pure LiNbO3 at about 3458 cm-1, 3476 cm-1, and 3492 cm-1. However, the absorption peaks of Er3+doped LiNbO3 was found at 3451 cm-1, 3478 cm-1, and 3490 cm-1. The OH- absorption peaks were considered to relate to the stretching vibrations of protons located at 336 pm O-O bonds in oxygen triangles nearest to the Li site.
