In an aggregated gold nanoparticle (AuNP) sol substrate, rhodamine S (RhS) exhibited a surface-enhanced Raman scattering (SERS) peak at 1503 cm(-1). Based on the ozone oxidization and RhS-I-3 particle reactions, 1.56-62.5 nmol L-1 of O-3 can be determined by SERS, with a detection limit of 0.9 nmol L-1.
