Surface plasmon resonance (SPR) of metal nanostructures has broad application prospects in the fields of sensing, energy, catalysis and optics. This paper reports a graphene-assisted method for preparing large-scale single-crystal Ag(111) nanoparticle (NP) arrays based on the ion implantation technique. By surface periodic patterning treatment and annealing of the implanted sample, regularly arranged Ag NPs can be prepared on the sample surface. A new application for graphene is proposed, that…

Synthesis and Characterization of Graphene–Silver Nanoparticle Hybrid Materials
TLDR
A simple method for the synthesis of graphene–silver nanoparticle hybrids on highly oriented pyrolytic graphite (HOPG) substrates is reported, which shows that the Ag NPs completely sandwiched between graphene and HOPG do not sulfurize, even after one year.

Single-Layer Graphene as a Barrier Layer for Intense UV Laser-Induced Damages for Silver Nanowire Network.
TLDR
It is demonstrated that SLG can shield metallic nanostructures from intense laser radiation that would otherwise ablate them, and particular damage-free and ablation-free laser-based nanomanufacturing of hybrid nanostructure might be sparked off by application of SLG on functional surfaces and nanofeatures.

TLDR
A new approach for the fabrication of ultraflat single-crystal graphene using Cu/Ni (111)/sapphire wafers at lower temperature is reported and it is found that the temperature of epitaxial growth of graphene usingCu/ Ni (111) can be reduced to 750 °C, much lower than that of earlier reports on catalytic surfaces.

Polarized plasmonic enhancement by Au nanostructures probed through Raman scattering of suspended graphene.
TLDR
It is found that single layer graphene is suspended across the dimer cavity and provides an ideal two-dimensional test material for the local near-field distribution and a Raman enhancement of the order of 10(3) originating from the cavity.
