Abstract

The samples of Zn_1-xFe_xO (0.00≤x≤0.10) were synthesized by co-precipitation method. The structure, optical and ferromagnetic properties were examined using X-ray diffractometer, infrared spectrometer, UV-Vis spectrophotometer, fluorescence spectrometer and vibrating sample magnetometer. The results showed that all the samples exhibited the hexagon wurtzite structure without any secondary phases. The absorptivity of samples reached to 95% in ultraviolet bands and the absorption rate in visible bands increased obviously with doping, and the band gap of Zn_1-xFe_xO decreased from 3.20eV to 3.11eV. The photoluminescence characteristics of Zn_1-xFe_xO showed the ultraviolet emission and blue emission peaks. Evident reduction of the photoluminescence intensity was caused by Fe doping, while the location of the main peaks did not move. The samples exhibited obvious room temperature ferromagnetism and the magnetism decreased with the increasing of Fe concentration.
