摘要
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.
