| dc.description.abstract | Ultrasound pyrolysis spray technique is used to prepare single-phase thin flms of Zn1−xCoxO (x=0–22 at.%). The hexagonal wurtzite structure of the flms is confrmed by X-ray difraction with an average crystallite size estimated in the range of 18–30 nm. The compound structure and stoichiometry of the flms are further characterized by energy-dispersive spectros copy (EDAX). The spectrum analysis agreement great chords between the expected and measured Co atomic content in the flms indicating an efective doping. The results also reveal a high solubility of Co into ZnO solid solution at about 14 at.%. For the optical proprieties, the bandgap energy decreases due to the presence of high concentrations of localized states in the thin flms. The photoluminescence spectra of all the samples exhibited a broad emission in the visible range. In addition, the magnetic properties of Zn1−xCoxO thin flms are found to be strongly infuenced by Co doping. | |
