Well-aligned ZnO nanorod arrays with room temperature ferromagnetism were prepared on glass substrate through hydrothermal method. The as-prepared nanorod arrays were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), photoluminescence (PL) spectrum, and magnetization measurements. The XRD and SEM results indicated that the ZnO nanorods are with the wurtzite structure and exhibit preferential (002) orientation withc-axis perpendicular to the substrate surface. The PL results suggested that the possible defect in the as-prepared ZnO nanorod arrays might beVZn,Oi, orOZn. The first-principles calculations reveal that the room temperature ferromagnetism may result from theVZndefects present in the ZnO nanorod and the hybridization of the Zn 3d states with O 2p states is responsible for the half-metallic ferromagnetism in ZnO nanorod.

Mn-doped ZnO nanorod arrays (ZnO:Mn NAs) have been prepared by a solution deposition method and the effect of Mn modification has been studied. Microstructure, morphology, photoluminescence characteristics of the ZnO: Mn NAs were investigated using X-ray diffraction, field emission scanning electron microscopy, fourier transform infrared spectrometer, fluorescence spectrophotometer. XRD analysis shows that ZnO:Mn NAs are wurtzite phases and highly c-axis oriented. As for ZnO:Mn NAs, obvious changes of photoluminescence intensity are observed at the wavelength of 395nm and 550 nm, according to Mn/Zn atomic ratio.
