摘　　要：By the combination of high-temperature organometallic synthesis and phase transfer through complete ligand-exchange withmixed phosphate, highly water-dispersible Fe3O4nanoparticles with narrow size distribution are obtained, which show appli-cable response to magnetic field. IR and -potential characterization of this system provides insights into ligand structures onparticle surface.By the combination of high-temperature organometallic synthesis and phase transfer through complete ligand-exchange withmixed phosphate, highly water-dispersible Fe3O4nanoparticles with narrow size distribution are obtained, which show appli-cable response to magnetic field.
