Abstract

A new absorption band at 3506 cm-1 has been observed in LiNbO3 doped simultaneously with Mg and Cr. The band is distinctly separated from the well known band at 3485 cm-1 in undoped crystals and from that near 3540 cm-1 due to MgOH complexes. The new absorption band is interpreted as an OH- vibration in a Cr3+OH-Mg2+ association. Variations in the UVVIS and IR spectra suggest that Cr4+ ions are also present in the crystal.
