Shape-controlled synthesis of silver nanostructures.

At room temperature, without any template and in the solid phase, shape-controlled silver nanostructures are synthesized using solid electrolyte RbAg(4)I(5) thin film under direct current electric field (DCEF) treatment. With different DCEF strengths, we have synthesized silver single-crystalline nanowires, nanotubes, nanoparticles and nanoframes. The growth mechanism and the relationship between the DCEF strength and the synthesized nanostructures are discussed briefly.
