Facile synthesis of graphene-coupled silver nanostructure-based hybrid SERS for trace-level SERS detection of thiram
Abstract
. The coupling of graphene with optimal silver nanostructure exhibits a significant enhancement in the SERS signal compared with the bare silver nanostructure substrate, with about one order more increase in the EF due to the enhanced plasmonic coupling induced by the incorporation of graphene and understood from the FDTD analysis. Graphene, with its Fermi level possibly modulated and subsequently tuned to align with HOMO-LUMO levels of thiram could be responsible for improved plasmonic coupling and hence increased SERS performance.
