Abstract
Section titled “Abstract”Advanced materials based on zinc and cadmium sulfides are obtained and certified as substitutional solid solutions with a hexagonal wurtzite structure. The structure and the bulk and surface spectroscopic, acid‒base, and adsorption properties are investigated, which enriches the knowledge of multicomponent diamond-like semiconductors. Studying the surface properties of the ZnS-CdS-system components reveals the average strength and concentration of active sites, their nature, relative contribution, features, and mechanisms of acid‒base interactions consistent with the adsorption ones. Consistent patterns of change in the bulk and surface properties with composition are established, which can be used to preliminarily evaluate the sensitivity and selectivity of the surfaces to gases of different electronic natures. Practical guidelines on the use of the synthesized materials with the optimum composition (with the lowest pHiso values) in the production of sensors for trace amounts of ammonia and other basic gases are given.
