Abstract
Graphene decorated with well-defined gold nanocrystals form functional nanocomposites that have many potential applications in electronics, optical sensors and Raman signal enhancers. These materials are commonly produced indirect reduction of gold precursors like HAuCl4 or KAuBr4 by graphene. However, in order to reduce surface energy, this generally forms approximately spherical, zero dimensional, gold nanoparticles. For tailorable electrical and optical properties, two dimensional gold structures such as nanoplates are usually obtained with the assistance of templates and surfactants. Unfortunately, these processes are inefficient, complicated and time-consuming. Here, we demonstrate an in-situ, efficient and surfactant-free synthesis of ultra-thin (~20nm) and high aspect ratio (50:1) gold nanoplates. The synthesis includes two steps: (1) Oxidize graphene surfaces with atmospheric pressure plasma for ~30 seconds and (2) Directly reduce KAuBr4 solutions with the activated graphene for two hours. Experimental results from EDS, TEM and SAED show that the plates are pure gold and have a single crystalline FCC structure with {111} oriented basal planes. We also show that the Raman scattering signal from gold nanoplates deposited graphene was significantly enhanced by 10-fold.
