A metal–dielectric–graphene sandwich for surface enhanced raman spectroscopy

A metal–dielectric–graphene sandwich for surface enhanced raman spectroscopy

The Raman intensity of Rhodamine B (RhB) is enhanced by inserting a thin high κ dielectric layer which reduces the surface plasmon damping at the gold–graphene interface. The results indicate that the Raman intensity increases sharply by plasmonic resonance enhancement while maintaining efficient fl...
