Photoactive ZnO–Al2O3 Transparent Coatings and Nanocomposites Prepared by a Simple Polymer-Salt Synthesis

Аннотация

The article presents the study of ZnO–Al₂O₃ thin coatings prepared by a polymer-salt method using the polyvinylpyrrolidone and zinc nitrate and tin (IV) chloride solutions. The materials were studied by spectroscopic methods and SEM analysis. It was found that prepared coatings have transparency in visible spectral range and demonstrate the ability to generate singlet oxygen under UV irradiation.
