Figure 6

SEM image of Au plates obtained at 150°C with the different [CTAB]/[HAuCl4] molar ratios of: (a) 5, (b) 3, and (c) 1. (d) Au plates obtained with the [PVP]/[HAuCl4] molar ratio of 30 and absence of CTAB. Inserted in (b) is a magnification image for the edge facet of box part, indicating the basal planes are perpendicular to the side facets.
