Abstract

We introduce a unique surface-enhanced Raman scattering (SERS) substrate, which is made of hierarchical nanoarrays comprising silicon nanowires (SiNWs) decorated with silver nanoparticles (AgNPs). SiNWs arrays were produced through chemical etching of n-Si(100) wafer, while AgNPs were directly grown on SiNWs through galvanic redox reaction without any organic contamination. Solid surface extinction spectrum revealed strong surface plasmon absorption in a broad range (from 200 to 1000 nm) indicating that surface plasmon induced by the incident laser could resonate with incident and scattering photons in a broad wavelength region. The 3D arrangement of the AgNPs
