| 摘 要： | 采用氧化铝模板由交流电沉积制备纯银纳米线.然后借助化学还原法,在已制备好的银线表面包裹不同厚度的金壳层,得到具有核壳结构的AgcoreAushell复合纳米线.电子显微镜(SEM,TEM)显示该复合结构纳米线表面形貌与加入的金盐量有关,而且包裹层较薄的复合纳米线表面存在大量的孔洞.循环伏安测试表明,具有孔洞效应的复合纳米线经多次循环扫描后即可过渡到无孔洞效应的表面.以对巯基苯胺(PATP)作为探针分子的表面增强拉曼光谱,可用于表征纳米材料的表面结构.

| Abstract: | Agcore Aushell nanowires with different thicknesses were prepared by combining template synthesis and chemical reduction method,and characterized by SEM and cyclic voltammetry(CV).The CV results revealed that the AgcoreAushell nanowires with pinhole were transferred to pinhole free structure after several potential scans.By using thiophenol(TP)and p-aminothiophenol(PATP)as probe,the surface enhanced Raman scattering(SERS)effect was investigated on the core-shell nanowires.The results indicated that AgcoreAushell nanowires could be served as a potential SERS substrate,and the difference in the spectral feature of PATP adsorbed onto Au and Ag nanowires enable us to diagnose the pinhole effect of core-shell nanowires by SERS. |
