Co2+/Dy3+掺杂纳米立方Fe3O4的热还原制备及磁靶向滞留性能
Thermal Reduation Preparation of Co2+/Dy3+Doped Cubic Fe3O4 and Their Magnetic Targeting Retention
摘要
Abstract
Co2+/Dy3+ doped Fe3O4 nanoparticles(MxFe3-xO4) were synthesized by the thermal reduction and co-precipitation methods . The structure, morphology and magnetic properties of Mx Fe3-x O4 were characterized by means of X-ray diffractometer ( XRD ) , transmission electron microscope ( TEM ) and vibrating sample magnetometer(VSM). The results show that the dopants did not change the maternal symmetry, and the mater-nal morphology gradually transformed from cube to sphere. The Mx Fe3-x O4 cubic magnetic particles have maxi-mum saturation magnetization of 7665 and 7021 A · m2 · kg-1 , respectively, when Co2+ actual doping amount is equal to 044 and Dy3+actual doping amount is equal to 005 Compared with the superparamagnet-ic Fe3 O4 , the cubic high magnetic doped Fe3 O4 nanoparticles showed a high retention rate in the simulated magnetic fluid magnetic targeting experiment in vitro.关键词
