Features of the Morphology and Properties of Disperse ZnO Powders, Obtained by Polymer-Salt Synthesis Using Polyvinylpyrrolidone

This study examines the features of the morphology and properties of disperse ZnO powders obtained by polymer-salt synthesis using polyvinylpyrrolidone (PVP). The processes of the thermal evolution of materials during the synthesis of powders are studied by differential thermal and thermogravimetric analysis. The crystal structure and morphology, as well as the luminescent and adsorption properties, of the synthesized nanopowders are studied by X-ray diffraction and electron microscopy analysis, as well as optical and luminescence spectroscopy. It is established that the addition of PVP reduces the size of the formed ZnO crystals and has a significant effect on the morphology, as well as the luminescent and adsorption properties, of the materials.
