摘要：

Copper nanoparticles have been prepared by pulsed wire discharge in several ambient gases. The experimental results of the particle size distribution and discharge behavior are discussed in terms of ambient gas species selection for particle size control. Scanning electron microscopy and voltage and current measurements were performed for the evaluation. It was found that temperature diffusivity and the breakdown voltage of the ambient gas are important factors for the availability of ambient gas species selection for particle size control.
