中文摘要：

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,对纳米银胶增强拉曼散射信号的机理进行了详细的研究。

英文摘要：

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 time were explored using rhodamine 6G（R6G） as a probe molecule. The results show 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 R6 G studied silver nanoparticles to investigate the effect of surface enhancement Raman. Meanwhile,we studied the mechanism in the process of enhancement by silver nanoparticles.
