Fund Project: We gratefully acknowledge the support to this research from the National Natural Science Foundation of China for financial support of this research (No. 60371027, 60171005, 90406023, 90406024 and 20573019).

Single-crystalline, regular-edged gold nanoplates are synthesized through chemical reduction of AuCl₄^- by a suitable amount of citrate at room temperature, without additional capping agents or surfactants. The suitable molar ratio of sodium citrate to HAuCl₄, low reaction temperature and the presence of natural light are critical factors for the formation of the regularly shaped nanoplates.
