Stokes shift nanostructures

Optimal SERS enhancement therefore requires that both the incident radiation at COinc and the Stokes Raman shifted radiation at cOs = cOinc vib are in resonance with the LSPR peak of the metallic nanostructure. Generally, the nanostructures with typical dimensions 30-100 nm are necessary to fulfil the conditions of LSPR resonance with visible light. LSPR strongly depends on the size and shape of nanostructures (Schatz et al. 2006) and is also strongly modified for closely spaced...
