Ag-doped HfO{sub 2} thin films via sol–gel dip coating method

In this study, undoped and Ag-doped HfO{sub 2} thin films were deposited on glass substrates by means of sol–gel dip coating method. These films were then thermally annealed at 500 °C for 1 h. The structural and optical properties of undoped and Ag-doped HfO{sub 2} thin films were characterized by X...

Summary:In this study, undoped and Ag-doped HfO{sub 2} thin films were deposited on glass substrates by means of sol–gel dip coating method. These films were then thermally annealed at 500 °C for 1 h. The structural and optical properties of undoped and Ag-doped HfO{sub 2} thin films were characterized by X-ray diffraction, UV–Vis spectrometry and scanning electron microscope. The results of this analysis were compared and interpreted with the results obtained in literature by various methods of coating with HfO{sub 2}. The X-ray diffraction peaks of the films paired with monoclinic HfO{sub 2} crystalline peaks. The refractive indices of the films decreased with doping Ag, at 500 nm wavelengths. The optical band gap values of Ag-doped HfO{sub 2} thin films increased with doping Ag. The porous structures were observed on the surface films, especially with 5% Ag doping.
