摘    要:采用一步微波辅助法制备了纳米银胶,并利用紫外-可见吸收光谱,透射电子显微镜(TEM)和原子力显微镜(AFM)等检测手段对纳米银胶相应的性质和结构进行了表征。利用罗丹明6G(R6G)为探针分子,考察了不同反应时间制备的纳米银胶对拉曼散射(SERS)的表面增强效果。结果表明,纳米银胶可以提高拉曼散射的信号强度,比较和分析了增强后的拉曼光谱。同时,我们对纳米银胶增强拉曼散射信号的机理进行了详细的研究。

关 键 词:微波辅助法    纳米银胶    拉曼表面增强

Abstract:A one-step microwave-assisted method was used for the synthesis of silver nanoparticles, and the corresponding nature and structure of silver nanoparticles were characterized by UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), and atomic force microscopy (AFM). Raman scattering activities of silver nanoparticles with different reaction times were checked by using rhodamine 6G (R6G) as a probe molecule. The results showed that the intensity of surface enhancement Raman scattering (SERS) signals could be increased by silver nanoparticles. And then we made a comparison on SERS spectra of R6G molecules adsorbed on three kinds of silver nanoparticles to investigate the effect of surface enhancement Raman. Meanwhile, we have also performed substantially studying of the mechanism in the process of enhancement by silver nanoparticles.
Keywords:Microwave-assisted  method  Silver  nanoparticles  Surface  enhancement Raman  scattering
