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.展开更多

The result suggests that the two molecules, except the loss of portons,are nondissociatively chendsorbed on copper and that adsorption occurs solely throughinteraction of the introgen atom with the copper substrate in the bodazole moiety. Theirdifferent abillties to act as corrosion inhibitors axe discussed from the viewpoint of thecyclic voltanunogram and the structu-ral information obtained from SERS. An adsorptionprocess for the molecules on the copper surface is also discussed.展开更多
