AbstractPlasmonic graphene is fabricated using thermally assisted self‐assembly of silver nanoparticles on graphene. The localized surface‐plasmonic effect is demonstrated with the resonance frequency shifting from 446 to 495 nm when the lateral dimension of the Ag nanoparticles increases from about 50 to 150 nm. Finite‐difference time‐domain simulations are employed to confirm the experimentally observed light‐scattering enhancement in the solar spectrum in plasmonic graphene and the decrease of both the plasmonic resonance frequency and amplitude with increasing graphene thickness. In addition, plasmonic graphene shows much‐improved electrical conductance by a factor of 2–4 as compared to the original graphene, making the plasmonic graphene a promising advanced transparent conductor with enhanced light scattering for thin‐film optoelectronic devices.
