Abstract
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 X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) spectroscopies. It has been found that for the impurity concentration used (1% of TiO2 and 0.1% NiO in the melt) both ions, Ti4+ and Ni2+, are incorporated at the Li site of the LiNbO3 lattice.Keywords
