Study of Chemical Enhancement in SERS from Au Nanoparticles Assembly
Abstract:
ld nanoparticles were assembled on ld substrates with the self-assembled monolayer(SAM) of p-minothiophenol(PATP). AFM measurements disclose that ld nanoparticles are scattered over the surface of the substrate with a submonolayer coverage. The Raman signal of the coupling layer, the SAM of PATP, can be well observed. Potential-dependent measurements were performed to study the chemical enhancement in SERS of such a system. Based on the supposition that the direction of charge transfer is from ld nanoparticles to PATP, it is deduced that Herzberg-Teller contribution has ruled in the SERS of such a system.
