Abstract

The current work addresses the understanding of the shape transformation of silver and gold nanorods towards more spherical nanostructures in aqueous suspension at ambient temperature. The shape transformation process was characterised using UV/Vis absorption spectroscopy, scanning electron microscopy (SEM), anodic stripping voltammetry and high resolution transmission electron microscopy (HRTEM). The increase in the particle number density during ageing indicates that the rods break spontaneously in smaller particles by surface defect induced ripening.
