The subject of research: construction and analysis of phase diagrams, sections and individual sections of complex chalcogenide and chalcohalide systems, thermodynamic properties, conditions and mechanisms of solid-phase synthesis of compounds; establishing the dependence of the structural, optical and morphological properties of ZnO and ZnS nanostructures on the technological parameters of the synthesis. The purpose of the research: determination of the synthesis conditions, thermodynamic properties, phase composition and specific ionic conductivity parameters of chalcogenides and chalcohalides of the Ag–BII–XVI, Ag–XVI–YVII, Ag–BII–DIV–XVI, Ag–BII–XVI–YVII та Ag–DIV–XVI–YVII systems; establishment of structural, optical and morphological properties of ZnO and ZnS nanostructures obtained by the electrochemical synthesis, and their dependence on the technological synthesis parameters. Research methods: direct one-temperature synthesis method, low-temperature synthesis of an equilibrium set of phases in the positive electrode of an electrochemical cell, X-ray phase analysis, differential thermal analysis, differential scanning calorimetry and thermogravimetric analysis, scanning electron microscopy, energy dispersive X-ray analysis, EMF measurement method, thermodynamic analysis, photoluminescence and Raman spectroscopy Product Description popup.authors Moroz Mykola V.
