Facile Synthesis of Silver Nanoparticles Useful for Fabrication of High-Conductivity Elements for Printed Electronics

Abstract

A facile synthesis of stable silver nanoparticles having a particle size of 2, in the presence of a 1-alkylamine, such as C₁₆H₃₃NH₂, in toluene at 25−60 °C. Spin-coated thin films or printed electronic features of alkylamine-stabilized silver nanoparticles could be easily converted at 120−160 °C into highly conductive films or elements with conductivity of 2−4 × 10⁴ S cm^-1. Organic thin-film transistors with printed silver source/drain electrodes of this nature exhibited field-effect transistor properties which are similar to those of the devices using vacuum-deposited silver electrodes.
