Ho-doped lithium niobate thin films: creation and characterization

Résumé

Different concentration of Ho3+ions doped lithium niobate powders and alkoxides were synthesized by solid and wet reactions respectively. Obtained powders and fired alkoxides were investigated by means of X-ray diffraction analyses and corresponding lattice parameters were calculated. Thin films of LiNbO3:Ho3+ were grown by Sol-Gel method on a sapphire substrate of (001) orientation. Structural modifications of obtained thin films were investigated by highresolution x-ray reciprocal space mapping. The reciprocal space maps were collected in the proximity of the symmetric (006) and asymmetric (018) Bragg reflections of the sapphire substrate. By comparing the maps obtained from different independent Bragg reflections, the deformation matrix was solved and lattice parameters of thin films were calculated.
