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.
The two-step or three-step method was used to prepare two-layer or three-layer carbon spheres templates respectively, Zn ions and Mn ions in the solution were adsorbed on the template and then calcined, TEM and SEM showed that Plate structure of multi-layer Mn-doped ZnO vesicles. EDS display Mn in ZnO doped content of about 1% .The sample has room temperature ferromagnetism, saturation magnetic susceptibility (Ms) and coercive field (Hc) were 0.032A .m2 / kg, and 0.781 kA / m. This Mn-doped ZnO nanovester structure provides a perfect combination of the novel vesicle structure and the magnetic properties of ZnO.
