Graphene–silver nanohybrids for ultrasensitive surface enhanced Raman spectroscopy: size dependence of silver nanoparticles

The surface-enhanced Raman scattering (SERS) mechanism of graphene-silver (GE-Ag) nanohybrids was investigated by studying the Raman signals of rhodamine 6G (R6G) adsorbed onto nanohybrids with different sizes of Ag nanoparticles (NPs). The results showed that the SERS intensity ratios between GE-Ag...
