摘要：

In this study, conducting and transparent indium-doped zinc oxide (ZnO) thin films have been deposited on glass substrates by the micro-spray technique First, zinc oxide layers were obtained by spaying a solution of propanol and zinc acetate in acidified medium, Alternatively, some of the obtained films were doped with indium (In) at the molar rates of. 1%, 2% and 3% In addition to the classical structural investigated using XRD, AFM and SEM techniques. microhardness Vickers (Hv) measurements have been carried out along with comparative morphological prospecting. The specific gases sensitivity-related surface morphology of the doped ZnO compounds was favorably different from that of the non-doped ones, and showed a thin overlay structure Results were compared to those recorded for similar ytterbium-doped material.
