Synthesis of Silver Nano-Wires Without Seeds by the Polyol Process

Abstract

Nano-scale materials have generated significantly scientific interest due to their unique optical, electrical and magnetic properties. The properties of nano-material are strongly dependent on the size and morphology of the particles. Therefore, it is very important to finely control the size and morphology of the nano-materials. In this work, one-dimensional structured silver nano-wires were synthesized on slide glass by polyol process without seeds. It was found that silver nano-wires were formed in presence of polyvinylpyrrolidone as capping agents. The obtained silver nano-wires were well-high mono-dispersed. Morphology of these nano-wires was changed by controlling the reaction temperature.
