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.

Key words： nanostructures; doping; oxides; magnetic materials
