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.
