Surface plasmon resonance of Au nanoparticles causes, among other optical effects, the enhancement of Raman signal known as SERS (surface-enhanced Raman scattering) and the increase of local temperature. In this work, we present an experimental (SERS)/theoretical (Mie theory) study of such effects for cresyl violet (CV) adsorbed on Au nanoparticle clusters.
