以阳极氧化铝为模板通过电泳沉积法制备Zn0.95Co0.05O纳米线和纳米管,并对电泳沉积法制备纳米线(管)的机理进行研究。系统的结构表征表明所得的纳米管和纳米线是由8～15nm的纤锌矿纳米晶构成的多晶结构,Co2+离子以代位掺杂形式掺入晶格,取代了晶格中的Zn2+离子。磁性表征显示制备的纳米线和纳米管具有室温铁磁性。由于Co在纳米线(管)中表面择优分布,纳米管的磁性明显高于纳米线。 Zn0.95Co0.05O nanowires and nanotubes were prepared by electrophoretic deposition using anodic alumina as a template, and the mechanism of nanowires (tubes) prepared by electrophoretic deposition was studied. The structural characterization of the system shows that the obtained nanotubes and nanowires are polycrystalline structures composed of 8-15 nm wurtzite nanocrystals. The Co2 + ions are doped into the lattice as the substituting doping, replacing the Zn2 + ions in the lattice. Magnetic characterization showed that the prepared nanowires and nanotubes have room temperature ferromagnetism. Due to the preferential surface distribution of Co in the nanowire (tube), the nanotube magnetism is significantly higher than that of the nanowire.
