Abstract

Zn _1-xFe _xO (x=0-0.05) nanoparticles were synthesized without a catalyst by a two-step method. Fe was doped into ZnO by a source of metallic Fe sheets in a solid-liquid system at 80 °C, and the Zn _1-xFe _xO nanoparticles were obtained by annealing at 300 °C. X-ray diffraction, X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy were used to characterize the structural properties of the as-grown Zn _1-xFe _xO. The optical properties were determined by Infrared and Ultraviolet-visible spectroscopy. The results confirm that the crystallinity of the ZnO is deteriorated due to Fe-doping. XPS results show that there is a mixture of Fe ⁰ and the Fe ³ in the representative Zn _0.95Fe _0.05O sample. The optical band gap of Zn _1-xFe _xO is enhanced with increasing of Fe-doping. Room temperature ferromagnetism was observed in all the Fe-doped ZnO samples.
