Abstract

In the present work we describe a new type of gold nanoparticle. The particle shape corresponds to a truncated icosahedron which in some orientations appears as an asymmetric decahedron. The particle structure is discussed and the corresponding high resolution electron microscopy images are calculated for the optimum defocusing condition in several orientations. Experimental images of gold nanoparticles are shown that corroborate the truncated icosahedron structure. The evidence suggest that indeed this particle is formed in experimental growth conditions in which the equilibrium shape is achieved.
