Disk-shaped silver nanoparticles with tunable aspect ratio have been synthesized by photoreduction of silver ions by citrate. This growth mechanism is driven by the light-induced polarization. Hence, shape and aspect ratio of these particles are controlled by the irradiation wavelength due to the shape dependence of the plasmon resonance.
