We have employed low cost-thin films of reduced graphene oxide (rGO) with Ag
nanoparticle hybrids as surface enhanced Raman scattering (SERS) substrates. The hybrids
are prepared by a simple one step liquid/liquid interface method. These hybrid films offer
SERS hotspots to detect Rhodamine 6G (R6G) molecules till 1 nM concentration with 1
second accumulation time. The enhancement factor is of the order 10 8. This excellent
SERS enhancement is due to coupled mechanism of surface plasmon, charge transfer and …
