Abstract

We investigate the transformation of single crystal gold nanorod surface morphology over extended growth times. After initial rapid anisotropic growth and disappearance of {111} bridging facets, the aspect ratios converge across AgNO₃ concentrations. The surface morphology transitions from faceted to curved. These observations imply the final aspect ratio has little dependence on the AgNO₃ concentration, consistent with primary control of the AgNO₃ over aspect ratio occurring at the symmetry breaking point.
