Abstract
The effect of the preparation procedure on the defect structure of LiVO3 and Li1-xCo0.5xVO3 (0 <x ≤0.35) solid solutions was studied by IR spectroscopy and electron spin resonance. The polycrystalline materials prepared by solid-state reactions, slow melt cooling, and melt quenching were all found to contain significant amounts of structural defects. The concentration of V(IV) centers and the distortions of the V-O polyhedra in the solid solutions were shown to correlate with oxygen deficiency and cobalt content.
