The Synthesis and Characterisation of Nanocrystalline Lithium Niobate [PDF]

Radiation Effects and Defects in Solids, 2003
Nanocrystalline LiNbO3 powder with grain sizes below 10 nm have been successfully prepared using wet chemical techniques, namely the polymer precursor method (and variations of it) and a double alkoxide sol-gel method. These have grain sizes of 4.5 nm and 1.6 nm respectively which, as far as we are aware, are the smallest nanocrystals of LiNbO3 ...

Selfenhancement in lithium niobate

Optics Communications, 1989
Abstract A simple linear theory for selfenhancement in transmission geometry is presented. The results are compared with measurements in lithium niobate. We obtain good overall agreement between theory and experiment.

Lithium niobate bicrystal

Ferroelectrics, 1981
Abstract In studies directed towards improving the basic understanding of the influence of grain boundaries upon the properties of electroceramic materials, studies are being made of artificial planar boundaries created in single domain ferroelectric lithium niobate crystals by thermally bonding carefully polished (001) surfaces.

Hydrogen in lithium niobate

Advances in Physics, 1996
Abstract This article reviews the current knowledge on the main properties and applications of hydrogen in LiNbO3. The review is divided into three parts. The first is devoted to general properties such as methods of defect production and control, techniques used for their detection and characterization, as well as interactions with other lattice ...

Two-photon apodization in lithium niobate

Optics Letters, 1998
We demonstrate a novel apodization technique for holographic data storage using two-photon recording in stoichiometric lithium niobate. The gating light-intensity profile is used to achieve grating apodization inside the bulk of the crystal during recording in the transmission geometry.

Imaging with lithium niobate/epoxy composites

Ultrasonics, 2004
Lithium niobate, LiNbO3, is a very promising material for high temperature applications in non-destructive testing because of its high Curie temperature. However, for commercial applications LiNbO3 has often been neglected because of its low electromechanical coupling coefficients.
