摘　　要：以硝酸铈为铈源,聚乙烯吡咯烷酮为表面活性剂,在碱性水相条件下制备CeO2纳米微晶。用XRD、SEM和TEM对产物进行表征,结果显示得到的CeO2纳米微晶具有立方晶型结构,分散性好,直径为10～20nm。此外,用紫外-可见分光光度计对样品的紫外吸收性质进行了考察。The CeO2 crystals were synthesized by a solution method using Ce（NO3）3 · 6H2O and polyvinylpyr- rolidone（PVP） as precursors. X-ray powder diffraction, field emission scanning electron microscopy and transition electron microscopy were used to characterize the obtained samples. The results showed that cubic crystalline CeO~ nanopartieles of 10~20nm in size and with good monodispersity were obtained using this method. In addition, the UV absorption properties of the CeO2 nanoparticles were studied by UV-Vis spectroscopy.
