Abstract

Chemical compounds based on A^IIB^VI are widely used as phosphors and photosensitive materials for VIS and IR spectral range. It is of common knowledge that functional properties of A^IIB^VI based materials are strongly depended on a deviation from stoichiometry which could be varied within 10^-2 mol.%. At the same time an influence of nonstoichiometry (native point) defects on structure-sensitive properties is no less than that of dopants. Besides phosphors A^IIB^VI powders are applied as inorganic pigments, which color and tint determined both a (CdTe)_x(CdSe)_1-x solid solution composition and a deviation from stoichiometry.
