Magnetic and optical properties of Co-doped ZnO nanorod arrays

In this study, Zn1−xCoxO nanorod arrays were deposited on Si substrates by magnetron sputtering followed by the hydrothermal method at 100 °C. The effects of doping concentration and hydrothermal growth conditions on the crystal structures, morphologies, magnetic and optical properties of the obtained Zn1−xCoxO nanorod arrays were studied. Surface characterization showed Zn1−xCoxO nanorod arrays with uniform and dense distributions along the...
