Monodispersed, spherical gamma-Fe2O3 nanoparticles with controllable size in large-scale were prepared by thermolytic decomposition of FeCl3.6H2O in aliphatic amines. The nanoparticles gave very stable colloidal solution in organic solvents and can be easily converted to water-soluble by a very simple route. Their characterisation was based on TEM microscopy, XRD, Mössbauer, and magnetic measurements. Furthermore, a small amount of Pt can lead to the formation of anisotropic gamma-Fe2O3 nanostructures.
通过在脂肪胺中热分解FeCl₃·6H₂O制备了尺寸可控的单分散球形γ-Fe₂O₃纳米颗粒，且可大规模制备。这些纳米颗粒在有机溶剂中形成非常稳定的胶体溶液，并且可以通过非常简单的途径轻松转化为水溶性。它们的表征基于透射电子显微镜（TEM）、X射线衍射（XRD）、穆斯堡尔谱（Mössbauer）和磁性测量。此外，少量的铂会导致形成各向异性的γ-Fe₂O₃纳米结构。
