Probing strong optical fields in compact aggregates of silver nanoparticles by SERRS of protoporphyrin IX

Abstract

TEM images and measurements of SERRS (surface-enhanced resonance Raman scattering) spectra as a function of the porphyrin concentrations in systems with unmodified and chloride-modified Ag nanoparticle and protoporphyrin IX are reported.
