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.
