Product Description:
Adding magnesium lithium niobate film between internal defect interaction with decreasing temperature
and increasing is the main reason for the vibration of OH^- absorption peak.
The cryogenic infrared spectra of pure lithium niobate and high magnesium doped lithium niobate crystals were measured, the absorption peak of OH^- was observed in the temperature dependence. The study found the OH^- vibration of pure lithium niobate absorption peak didn\'t change with temperature, while the OH^- vibration high MgO doped lithium niobate crystal absorption peak of the main peak position decreases with temperature to high wave number direction. Through the analysis of two kinds of crystal defects in different model and H + in the lattice of occupying, we suggest that high magnesium doped lithium niobate crystals of H^ + close to the high impurity defects (MgNb) ^3- distribution, directly involved in the defect group, completely different from the distribution of pure lithium niobate crystals of H^ +, which caused high magnesium doped lithium niobate crystals of OH^- vibration absorption peak changes with temperature.
