چکیده
Pure ZnO, Ag doped ZnO and Ag-Fe co-doped ZnOwere preparedusing thermal evaporation. XRD analysis confirms that all layers present a hexagonal wurtzite structure; however, there is small shift in the peaks position due to thedistortion of film’s lattice. Scanning Electron Microscopy (SEM) reveals morphological variation surfaces doping. Ag:ZnO films have nanostructured surface, Ag-Fe:ZnO showed smooth surface without any nanoparticles. Raman presence A1(LO), E2(high) andlocal vibrational modes (LVMs) for layers. Ultraviolet–visible spectroscopy (UV-VIS) shows good transparency bandgapdecreases with doping from 3.80 eVto 3.78 eV 3.70 eV,for pure films, respectively. The electrical properties confirm semiconductor nature resistivity around 1.4 Ω.cm, doping, behave like conductors 1.4´10-4Ω.cm 1.4´10-3Ω.cm, These results make thin materials photovoltaic application.

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...
