Raman and scanning tunneling spectroscopic investigations on graphene-silver nanocomposites
Graphene-silver (G-Ag) nanocomposites were prepared using liquid phase exfoliation of graphite flakes followed by a reduction of silver nitrate. The plasmonic characteristics of these nanocomposites are highly sensitive to the Ag concentration in the films.
