Investigation on the growth and structure of Fe-doped near-stoichiometric LiNbO3 crystal

Investigation on the growth and structure of Fe-doped near-stoichiometric LiNbO3 crystal The Fe-doped near-stoichiometric LiNbO3 crystal has been grown from the Li-rich melt by Czochralski method. The UV-Vis absorption spectra, IR transmittance spectra and X-ray diffraction were measured and used to study the defect structure of the crystal. Compared with that of congruent Fe:LiNbO3, in near-stoichiometric Fe:LiNbO3, the lattice parameter reduces, the basal absorption edge shifts towards shorter wavelength, and the OH stretching vibration absorption band shifts towards the lower wavenumber side (3466 cm−1) in the Fe-doped near-stoichiometric LiNbO3. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Science Springer Journals

Abstract

The Fe-doped near-stoichiometric LiNbO3 crystal has been grown from the Li-rich melt by Czochralski method. The UV-Vis absorption spectra, IR transmittance spectra and X-ray diffraction were measured and used to study the defect structure of the crystal. Compared with that of congruent Fe:LiNbO3, in near-stoichiometric Fe:LiNbO3, the lattice parameter reduces, the basal absorption edge shifts towards shorter wavelength, and the OH stretching vibration absorption band shifts towards the lower wavenumber side (3466 cm−1) in the Fe-doped near-stoichiometric LiNbO3.
