摘要：

Colloidal gold nanocups are synthesized through single-vertex-initiated gold deposition on PbS nanooctahedrons and subsequent selective dissolution of the PbS component. They possess strong magnetic plasmon resonance and exhibit remarkable orientation-dependent plasmonic properties when deposited on flat substrates. They can also effectively couple s-polarized light into the interfacial region between the nanocup and substrate.
