Abstract

Surface-enhanced Raman scattering (SERS) substrates based on gold or silver nanoparticles have been extensively investigated as they provide good surface plasmon resonances (SPR) property in the visible spectral region.1 Gold-silver nanoalloys have attracted intense attention for they combine the higher enhancement factor of silver nanoparticles and the more monodispersity of gold nanoparticles.2 Moreover, their physical and chemical properties can be flexibly tuned by varying the composition and atomic ordering as well as the size of the nanoalloys.3
