详细
The IR absorption spectrum of LiNbO3:Mg(5.05 mol %):Fe(0.009 mol %) crystals has been shown to be noticeably shifted (by ~50 cm–1) to higher frequencies, corresponding to stretching vibrations of OH– groups, in comparison with the spectrum of congruent LiNbO3 crystals. Analysis has shown that the shift is due to the formation of \({\text{Mg}}_{{{\text{Li}}}}^{ + }\)–\({\text{Fe}}_{{{\text{Nb}}}}^{{2 - }}\)–OH– and \({\text{Mg}}_{{{\text{Li}}}}^{ + }\)–\({\text{Mg}}_{{{\text{Nb}}}}^{{3 - }}\)–ОН– defect complexes.
