title: Metal ion redox potential plays an important role in high-yield synthesis of monodisperse silver nanoparticles.
abstract: A facile method is developed to prepare monodisperse silver nanoparticles in a much enhanced yield by adding a trace amount of Fe(3+) ions into the reaction of AgNO(3) with oleic acid and oleylamine. We propose that Fe(2+) ions speed up the nucleation and growth of silver nanoparticles due to the electron-transfer between Ag(+) and Fe(2+), in which Fe(2+) is from Fe(3+) reduced by oleylamine.
