Synthesis Of Go/Au/Ag Nanocomposite With Excellent Surface Enhanced Raman Scattering Effect

In this work, a nanocomposite (GO/Au/Ag) containing graphene oxide (GO) and Au/Ag nanoparticles was fabricated by in situ reduction for improved manipulation of their SERS effect. The uniform dispersion of Au/Ag nanoparticles were successfully generated on GO. Rhodamine 6G (R6G) as a Raman probe was used to investigate the SERS effect. Owing to the synergistic effect of the high localized surface plasmon resonance of Au/Ag, and chemical enhancement of GOs, the Raman intensities of R6G on GO/Au/Ag is several times as high as that on Au/Ag or GO/Au. GO/Au/Ag nanocomposites showed excellent Raman enhancement and appeared to be a kind of valuable material with potential application in SERS detection.
