Abstract

We report on the synthesis of Fe-doped ZnO with nominal composition of Zn0.99 Fe0.01 O by using a coprecipitation method. X-ray diffraction and selective area electron diffraction studies reveal a single phase wurtzite crystal structure without any secondary phase. Field emission transmission electron microscopy measurements infer that Zn0.99 Fe0.01 O have nanorod-type microstructures. Magnetic hysteresis measurement performed at different temperatures show that Zn0.99 Fe0.01 O exhibits a weak ferromagnetic behavior at room temperature. A detailed investigation of the electronic and local structure using O K -, Fe L3,2 near edge x-ray absorption fine structure suggests that Fe is substituting Zn in ZnO matrix and is in Fe3+ state.
