Abstract

The morphologies of Ag particles can be controlled between distorted sphere and prism by employing microwave-promoted reductions of highly concentrated 0.1 M silver nitrate in aqueous solutions. We can selectively synthesize either sphere-Ag or prism-Ag particles by changing only an additive, i.e., either trisodium citrate/formaldehyde or poly(N-vinyl-2-pyrrolidone) (PVP). The particle sizes and size distributions of sphere-Ag particles are strongly dependent on the concentration of trisodium citrate.
