From flat to deep concave: an unusual mode of facet control

Au particles with rhombic dodecahedron outlines and deep cavities are obtained by epitaxial growth from a triangular nanoplate. An unusual wrapping growth that combines ligand-promoted facet-selective growth and site-specific deposition is proposed. Such a templateless growth not only allows the extreme defect-tolerance, but also broadens the synthetic control at the nanoscale.

Automated summary

This paper describes the synthesis of gold nanoparticles with rhombic dodecahedron shapes and deep cavities through the use of triangular nanoplates. An unusual growth method that combines ligand-promoted facet-selective growth and site-specific deposition is proposed. This templateless growth not only allows for high defect-tolerance, but also expands synthetic control at the nanoscale.
