摘要：
The OH- absorption spectra and the UV absorption edges of LiNbO3 : Mg,Ti crystals have been measured. It is shown that Ti doping raises the Mg doping threshold level, and shifts the absorption edge towards longer wavelengths. The results can be explained by the formation of Mg2+Li-Ti4+Nb pairs after all antisite defects NbLi have been replaced.
