摘要： 通过两步或三步法分别制备两层或三层结构的碳球模板，在溶液中的Zn离子和Mn离子在模板上吸附后再进行煅烧.TEM及SEM显示，煅烧后得到完全复制碳膜板结构的多层Mn掺杂ZnO囊泡.EDS显示Mn在ZnO中的掺杂含量约为1％.样品具有室温铁磁性，饱和磁化率(Ms)及矫顽磁场(Hc)分别为0.032A·m2/kg及0.781kA/m.这种Mn掺杂ZnO纳米囊泡结构使新奇的囊泡结构和ZnO的磁性性能得到了完美的结合.

Abstract: A simple synthesis method of multi-shelled magnetic Mn-doped ZnO hollow nanospheres were developed with the assistance of carbon templates. The multispheres carbon templates were prepared with two- or three- synthetic steps. The Zn and Mn metal ions in the solution were absorbed onto the functional surface layer of carbon templates. The TEM and SEM images show single-, double-, and triple-shelled hollow spheres are obtained after calcination, and EDS spectrum shows the concentration of Mn is estimated to be 1%. The hollow nanospheres also have outstanding room temperature ferromagnetism magnetic properties. The saturation magnetization (Ms) is 0.032A·m2/kg, and the coercive field (Hc) is 0.781kA/m, respectively.
