Relationship between Length and Surface-Enhanced Raman Spectroscopy Signal Strength in Metal Nanoparticle Chains: Ideal Models versus Nanofabrication
Figure 2
FDTD calculations of the extinction spectra for 60 nm Au nanoparticle chains 1–9 nanoparticles in length. Nanochains in (a) have a 1 nm interparticle separation and are embedded in a medium with refractive index . Nanochains in (b) have a 1.5 nm interparticle separation and are embedded in a medium with refractive index .
