AP0838 Effect of Doping with Carbon Nanotubes on Structural and Optical Properties of Nanostructured Zinc Oxide Thin Films

Abstract

This research aims to study the effect of doping with carbon nanotubes on the structural and optical properties of zinc oxide films. Nanocomposite films of carbon nanotubes (ZnO:CNTs) with different weight ratios were produced using a vacuum deposition method on glass substrates. The structural, morphological and optical characteristics of the prepared thin films were studied. The prepared ZnO:CNT thin films showed polycrystalline structures with different CNT concentrations. The dominant orientation of these thin films produced in the hexagonal phase is (002). For pure ZnO thin films and ZnO thin films doped with 7% CNT, the typical crystallite sizes are 18.98 nm and 26.86 nm, respectively. As for the optical properties, it was observed that there was a decrease in the energy gap values when grafting with carbon nanotubes.
