| Abstract: | Silver nanoparticles of controlled shapes were prepared in an AgNO_(3)-TSC systerm by a simple photoreduction technique.The growth mechanism was investigated via UV-Vis and TEM techniques.The result indicates that UV radiation was necessary to reduce Ag~( ) from the solution and the particle morphologies strongly depended on the wavelength of the irradiation light.Sliver nanorods and nanoprisms were obtained under 253.7 nm and 365 nm ultraviolet(irradiations),respectively,while nanoprisms,(nanorods),nanocubes and nanospheres coinstantaneous appeared under 200~2 000 nm broad band irradiation. |
