| Abstract: | Shaped and dimpled: Silver nanocrystals enclosed by concave surfaces and thus high-index facets have been prepared by simply controlling the growth habit of Ag cubic seeds. Four types of concave nanocrystals, including octahedron, cube, octapod, and trisoctahedron, were obtained (see picture). |
| Keywords: | concave nanoparticles seeded growth silver surface‐enhanced Raman scattering |
