Abstract
On page 6322, J. F. Wang and co-workers report a wet-chemistry method for the preparation of colloidal Au nanocups and their plasmonic properties. The Au nanocups are prepared through single-vertex-initiated Au deposition on PbS nano-octahedrons and subsequent selective dissolution of PbS. Owing to the orientation-dependent coupling strengths, the obtained Au nanocups display orientation-dependent plasmonic properties and Raman enhancements when deposited on substrates.
