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.
