Electrochemical tuned scattering of gold nanostructure
Source abstract
Abstract
Abstract The ultrathin gold film and gold nanoprism immobilized on ITO electrodes displayed strong perturbed plasmonic scattering as the result of potential linear sweep and step applications. Although nanoscale surface structure strongly determines the potential-dependent plasmonic response of gold nanostructure, the universality of exponential fit for the differential scattering induced by the potential linear sweep indicates the same mechanism could be widely used to explain the effect of potential on the gold nanostructure. The larger scattering changed by the anodic potential step than cathodic counterpart is attributed to increased double layer capacitance due to the presence of adsorptive ion. The presence of potential controlled scattering indicates the tunability of localized surface plasmon resonance of gold nanostructure.
