Abstract
Three distinct site-specific Ag-coated Au nanoarrows are achieved by simply controlling the CTAC concentration of growth solution and analyzed with electron microscopy as well as elemental mapping. The CTAC concentration-dependent, facet-specific passivation represents a new strategy to design particle morphology as well as composition.
