Abstract

Three kinds of β-Sn-based plasmonic materials, including β-Sn nanoparticles, β-Sn/graphene hybrid structures and β-Sn@Ag core@shell nanoparticles, have been prepared to explore their near-field enhancement performance. The results indicate that such materials could act as traditional noble metallic nanostructures to support tunable resonance frequency. In addition, surface enhanced Raman scattering (SERS) determinations and corresponding calculations confirm that such novel plasmonic materials not only could serve as a SERS platform, but also could be an alternate efficient plasmonic material for the Si-based optoelectronic and/or photovoltaic devices by taking advantage of the near-field enhancement effect.
