Abstract
The research is centered on (CdTe)0.03(ZnSe)0.97 solid solutions. The article is aimed at developing innovative primary transducer material for semi-conductor sensors, investigating their surface physicochemical properties and evaluation their applicability in carbon monoxide diagnostics. Powders and nanofilms of (CdTe)0.03(ZnSe)0.97 solid solutions were obtained by isothermal diffusion and discrete thermal evaporation in vacuum. (CdTe)0.03(ZnSe)0.97 applicability in gas analysis was investigated. IR spectroscopy of multiple disturbed complete internal reflections and hydrolytic adsorption were used to study chemical composition and acid-base properties of (CdTe)0.03(ZnSe)0.97. Adsorption properties of the given material for carbon oxide (II) and oxygen were studied by the piezoquartz microweighing and volumetrically. The principles of adsorption, depending on the process conditions, were established. Based on the obtained experimental data, CO micro-impurities sensors were developed, the laboratory tests passed successfully
