| dc.abstract.en | The present study demonstrates the electrochemical and plasmonic features of gold structures grown in anodic TiO2 nanotubes by means of the electroreduction of Au+ species from a potassium dicyanoaurate electrolyte. The primary location of the electroreduced gold is in the gap between nanotubes, resulting in the formation of a gold/titania interface at the outer shell of the nanotubes. This unique configuration makes it possible to develop a specific shape of gold nanopore array, which is studied as a core− shell structure and standalone gold electrode after the selective dissolution of the titania matrix. Surface plasmon resonance, evaluated by finite-difference time-domain modeling, leads to strong electromagnetic fields and the consequent enhancement in light absorption and light scattering depending on the size, geometry, and composition of the nanostructure. The TiO 2 nanotube core promotes light localization in air and water due to its large refractive index. Numerical analysis indicates light E-field enhancement localized on the rims of titania nanotubes of the magnitude intensity of E2 > 100. |
