发布时间:2021-09-04 08:52
为了获得具有高饱和磁化强度的超顺磁性纳米材料,本研究成功通过微波辅助溶剂热法制备出锰掺杂和锌掺杂的超顺磁性氧化铁纳米簇(Mn-doped or Zn-doped ferrite nanoclusters, Mn-FNs or Zn-FNs),并利用透射电子显微镜(transmission electron microscopy, TEM)和动态光散射(dynamic light scattering, DLS)粒度仪对两者进行了初步的形态观察和粒径测定。之后,选择形态和分散性更好的Zn-FNs,进一步采用X射线衍射仪(X-ray diffractometer, XRD)、电感耦合等离子体质谱仪(inductively coupled plasma-mass spectrometry, ICP-MS)和振动样品磁强计(vibrating sample magnetometer,VSM)分别对其晶体结构、金属含量和磁学性质进行了体外表征。结果表明, Zn-FNs是由多个纳米粒子组装形成的团簇结构,形态圆整,分散性良好,粒径较均一,锌成功掺杂进入Zn-FNs中,晶体具有尖晶石结构,磁学性质优...
