| 摘 要： | 采用交流电沉积技术在阳极氧化铝(AAO)模板中沉积不同的金属纳米线, 以对巯基苯(1,4-BDT)为耦联分子, 通过自组装在模板内组装金属纳米粒子, 由此构建金属纳米线-分子-金属纳米粒子的异质结。以异质结内的分子为探针, 采用表面增强拉曼光谱(SERS)研究了异质结的增强行为，通过探针分子的SERS信号表达异质结的组成，并以异质结作为模型研究其SERS机理。研究结果表明该方法可成功构建异质结, 同一取向的异质结的SERS信号较随机取向的SERS信号强。

| Abstract: | In the present paper,the authors reported the assembly and SERS studies of a simple device unit of a metal nanowire-molecule-metal nanoparticles junction in an anodic aluminum oxide(AAO)template.The AAO template was fabricated by two-step electrochemical oxidation.Metals were filled into the pores by AC deposition.Then the AAO template with metal nanowires was immersed into the solution of 1,4-benzenedithiol(1,4-BDT),which was followed by the immersion into silver nanoparticles with appropriate diameter.1,4... |
