Abstract

Abstract

Ag nanostructures were successfully prepared on indium tin oxide(ITO) surfaces through electrochemical deposition. These nanostructures possessed uniform morphology. The concentration of AgNO₃, the nucleation potential, the growth potential and the addition of sodium citrate greatly affected the morphology and density of the as-prepared Ag nanostructures. Only when these parameters were reasonably set could Ag nanostructures with well-defined morphology and considerable density be obtained. Investigation on surface enhanced Raman scattering(SERS) activities of the as-prepared Ag nanostructures was also carried out under 633 nm excitation, using p-aminothiophenol (p-ATP) as the probe molecule. The results show that they can serve as potential SERS substrates.
