| Abstract: | The preparation of Ag nanoparticles with the non-spherical shape has been conducted from aqueous solution by photo induced conversion. Ag nanoprisms (80～120nm) and nanocube s(90～200nm) were respectively obtained in the presence of trisodiumcitrate (TSC) orpolyvinylpirrolidon (PVP). These Ag nanoparticles were single-crystals. The results showed that Ag nanoprisms had apreferential growth direction along the Ag(111) axis and Ag nanocubes had a preferential growth direction along the Ag(100) axis. By means of characterization with TEM, ED and UV-V is Spectra, the fundamental analyses and discussion about the changing causes of nanoparticles shape from spherical tonon-spherical have been carried out in the photo induced process. |
