摘　　要：常温常压下不加入任何催化剂,用两种不同的活性剂聚乙烯醇(Polyvinyl alcohol,PVA)和聚乙二醇 (Polyethylene glycol,PEG),在水溶液中通过电子束辐照可以成功地制备纳米Fe3O4粒子。通过紫外可见光 分光光度计(Ulwaviolct-visible spectrophotometer,UV)、X射线衍射(X-ray diffraction)、透射电子显微镜 (Transmission electron microscopy,TEM)对辐照后的样品的光学特性、结构、形貌、大小进行表征。发现不 同的活性剂对纳米粒子的尺寸会产生影响。Fe3O4 nano-particles have been successfully prepared by EB irradiation with two different actived agents, Polyvinyl alcohol （PVA） and Polyethylene glycol （PEG）, at room temperature and ambient pressure, without any kind of catalysts. The optical properties, component and morphology of the irradiated samples were measured by Ultraviolet-visible spectrophotometer （UV-vis）, X-ray diffraction （XRD） and Transmission electron microscopy （TEM）. The size of nano particles was found to be affected by the action of the different actived agents.
