摘要
We present a simple synthetic method for hexagonal Au nanoplates. Selective etching of specific facets of triangular nanoplates has led to the shape transformation. Also, the high quality of hexagonal Au nanoplates allows one to identify the higher-order plasmon resonance bands in addition to the dipole mode. © 2011 American Chemical Society.
