Electrochemical synthesis and analysis of SERS activity of gold nanoparticles films
- 化学化工－已发表论文 
Surface-enhanced Raman scattering(SERS)-active gold nanoparticles(AuNPa) films were prepared with a one-step electrochemical method. The orthogonal design was used to investigate the experimental conditions influencing the morphologies and the SERS activity of the AuNPs. A condition was found to obtain the optimal SERS activity. The SEM study reveals that the AuNPs films were composed of closely packed AuNPs. The Finite Difference Time Domain( FDTD) simulation result indicates that the coupling between particles plays an important role in the enhancement SERS of AuNPs.
