Clear doughnut-shaped far-field scattering patterns (DNSPs) for gold regular hexagonal nanoplates (AuHNPs) larger than 500 nm (distance between the two opposite edges) have been observed by dark-field microscopy imaging. This phenomenon was attributed to the edge effect, which can be further applied for reaction process monitoring.
