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 R6G studied silver nanoparticles to investigate the effect of surface enhancement Raman. Meanwhile, we studied the mechanism in the process of enhancement by silver nanoparticles.
