Electrochemical tuning of silver nanoparticles fabricated by nanosphere lithography

Nano Lett. 2005 Jul;5(7):1503-7. doi: 10.1021/nl050873x.

Abstract

An electrochemical method is developed to quantitatively modify and spectroscopically monitor the size and shape of Ag nanotriangles fabricated by nanosphere lithography (NSL) on an indium tin oxide (ITO) electrode surface. AFM and SEM results demonstrate that the preferential order of electrochemical oxidation for a nanotriangle is, surprisingly, bottom edges first, then triangular tips, then out-of-plane height.
