摘要: The structural environment of Ti and Ni ions incorporated into LiNbO3 single crystals during the growing process has been studied by using X-ray absorption spectroscopies: extended fine structure (EXAFS) near-edge (XANES) spectroscopies. It found that for impurity concentration used (1% TiO2 0.1% NiO in melt) both ions, Ti4+ Ni2+, are at Li site lattice.
