AbstractThe influence of nickel (Ni) dopant concentration of Ni-doped zinc oxide (ZnO) derived from sol gel technique on surface morphology, optical, luminescence, electrical and electronic transition properties were investigated. Surface morphology image of the thin films were obtained by using emission scanning electron microscope (FESEM). Optical and luminescence properties of the thin films were characterized by using Ultraviolet/Visible/Near infrared (UV/Vis/NIR) and photoluminescence (PL) spectrometer, respectively. Sheet resistance and work function of the thin films were determined by using four point probe and photoemission spectrometer, respectively. The thin film exhibits a smooth surface with grain size of 40–80 nm which depends on dopant concentration. All samples show a high transparency; over 80% in the visible range. Optical properties of the films are not affected so much by Ni dopant concentration. The sheet resistance of the thin film increases with the increase in Ni dopant concentration. The work function of the films obtained decreases after Ni dopant concentration exceeds 1%.
