Abstract

We report on the growth of silver nanoparticles (AgNPs) on graphene and study the applicability of the material for Surface Enhanced Raman Spectroscopy (SERS). Graphene has been shown to enhance the SERS signal with AgNPs by a factor of 2 - 17 due to charge transfer effects. Direct deposition of NPs can provide more uniform spatial distribution than spin on deposition of chemically derived NPs, and ALD has more potential for tuning the NP size and density if compared to evaporation. In experiments, the relative enhancement in R6G SERS signal was similar on both SIO2 and graphene templates, despite the lower density of the AgNPs on graphene. Most importantly, graphene was found to quench the background fluorescence by an order of magnitude when compared to SiO2.
