Rapid Thermal Synthesis of Silver Nanoprisms with Chemically Tailorable Thickness

Abstract

Silver nanoprisms with a unimodal size distribution are synthesized through a novel thermal route that permits some control over nanoprism-edge length (see Figure). The influences of citrate, poly(vinylpyrrolidone), H2O2, and NaBH4 on the nanostructures are described. This protocol allows control over nanoprism thickness, an architectural parameter not accessible via known preparative methods for such structures.
