A Novel Ultraviolet Irradiation Photoreduction Technique for the Preparation of Single-Crystal Ag Nanorods and Ag Dendrites

Single crystal Ag nanorods and elegant highly ordered dendriticsupramolecular nanostructures (see Figure) of Ag nanoparticles have been prepared via a novel ultraviolet photoreduction technique at room temperature using poly(vinylalcohol) (PVA) as protection agent. The concentration of both the PVA and AgNO3 play a significant role in the growth of the nanorods and dendrites.
