Fe(3)O(4)/carbon nanocomposite has been prepared by a facile chemical method, and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, fourier transform infrared spectroscopy and scanning electron microscopy. The fluorescent and magnetic properties of the sample were investigated by fluorescence spectroscopy and vibrating-sample magnetometer, respectively. The results indicate that the Fe(3)O(4)/carbon nanocomposite exhibit good photoluminescent (emission ranging from 425 to 550 nm) and strong magnetic (saturation magnetization of 44.2 emu/g) properties.
Fe(3)O(4)/碳纳米复合材料通过一种简便的化学方法制备，并通过 X 射线衍射、X 射线光电子能谱、透射电子显微镜、傅里叶变换红外光谱和扫描电子显微镜进行了表征。通过荧光光谱和振动样品磁强计分别研究了样品的荧光和磁性。结果表明，Fe(3)O(4)/碳纳米复合材料具有良好的光致发光（发射范围从 425 到 550nm）和强磁性（饱和磁化强度为 44.2emu/g）。
