Figure 2. A hypothesis for the plasmonic-mediated synthesis of single-crystalline Au NWs.

A schematic illustration for the light-driven formation of Au NWs including the plasmonic-mediated OA of Au NRs (primary building blocks) and 3D self-assembly of the secondary, tertiary and even higher-order building units, as well as the last stage of plasmonic heat treatment for recrystallization.
