Synthesis and characterization of transparent photocatalytic ZnO-Sm2O3 and ZnO-Er2O3 coatings

Abstract

This article describes the synthesis and characterization of transparent photocatalytic ZnO-Sm2O3 and ZnO-Er2O3 coatings. Transparent coatings were prepared by the liquid polymer-salt method and were studied by the optical and luminescence spectroscopy, SEM analysis and DSC method. Prepared coatings consist of small closely packed oxide nanoparticles and demonstrate high transparency in visible spectral range, photocatalytic properties and the ability to generate singlet oxygen under UV irradiation.
