Title: Facile synthesis of gold nanopuncheons with high-index facets and their SERS effects on Rhodamine 6G

Abstract

Highlights: • Au nanopuncheons with high-index facets have been prepared by seed-mediated growth. • The nanopuncheons are enclosed by 24 planes of (2 5 0), (3 0 1) and 2 (0 1 0) planes. • The nanopuncheons showed high SERS activity toward Rhodamine 6G. - Abstract: Au nanopuncheons with exposed high-index facets have been synthesized in high-yield by employing didodecyldimethylammonium bromide (DDAB) as surfactant in one-step seed-mediated growth. Transmission electron microscopy (TEM) characterization showed that the as-prepared Au nanopuncheons possessed 24 high index facets of (2 5 0), (3 0 1), and 2 (0 1 0) planes. Due to the high density of atomic steps and kinks in the structure, the Au nanopuncheons exhibited high surface enhanced Raman scattering (SERS) activity toward Rhodamine 6G.
