摘要

We present the study of ZnO-Al_2O_3 thin coatings and nanocomposites prepared by a polymer-salt method. The coatings demonstrate high transparency in UV-A (wavelength is about 300 to 400 nm) and visible spectral ranges and the ability to generate singlet oxygen under UV irradiation. The materials were studied by spectroscopic methods, scanning electron microscopy, and x-ray diffraction analysis. Obtained ZnO-Al_2O_3 films are thin (about 250 to 300 nm) and fully cover the glass surface. They contain oriented ZnO nanocrystals 23 to 35 nm in size. Coatings chemical compositions strongly affect their structure and spectral properties. Al_2O_3 additions change the coatings' crystal structure by decreasing ZnO crystal size and making their spatial orientation more random and enhance the transparency in near UV due to significant increase of bandgap values.
