摘　　要：在十二胺为表面活性剂、正辛烷为油相形成的油包水(W/O)型反胶束体系中,使Na2WO4和CdCl2发生反应,制得了长约2μm、带宽约20～30nm的CdWO4纳米带.测试了其拉曼光谱和荧光发射光谱,结果表明该CdWO4纳米粒子具有较好荧光发射性能.CdWO4 nanobehs with the length of about 2 μm and the width of about 20 - 30 nm were prepared in mieroemulsion systems using octane as oil, dodecylamine as surfactants. This nanostrueture was characterized by transmission electron microscopy （TEM） , X-ray energy dispersive spectroscopy （EDS）, fluorescence spectrophotometer. Photoluminesce analysis indicated the emission of the derived nanobeils was at about 428 nm, which was obvious blue shifted compared with the bulk CdWO4. Due to its inherent optical properties, CdWO4 nanobehs may play desirable role for various scintillation applications.
