The growth of zinc oxide nanocrystals on the zinc oxide thin film by chemical bath deposition

In the paper the low temperature deposition of zinc oxide called Chemical Bath Deposition (CBD) will be described. Zinc oxide nanocrystals grow on the thin layer of ZnO. In our investigation the thin film of ZnO was deposited using spin coating, on the glass substrate covered with thin film of Indium Tin Oxide (ITO). The goal of our research is to develop a cheap method of ZnO nanostructures growth, which will be applied in electrochemical gas sensors as a gas sensitive layer.
