## Abstract The shape transformation of silver triangular nanoplates induced by nanosecond laser pulses has been monitored using agarose gel electrophoresis as well as optical spectroscopy and electron microscopy. Laser irradiation truncates the vertices of the triangular nanoplates, having an aver
**Triangular nanoplates of silver** are prepared by irradiating aqueous dispersions of spherical silver colloids with visible light in the presence of both poly(vinyl pyrrolidone) and sodium citrate. These silver nanoplates serve as sacrificial templates to generate triangular rings of gold (see tra
