Abstract

Zinc oxide nanoparticles are nanomaterials that are expected to be applied in a wide range of fields such as solar cells, gas sensors and UV absorbers. It is known that various properties of nanoparticles depend on their size, shape and composition. Therefore, the synthesis method of nanoparticles is attracting attention. In this paper, we attempted to synthesize zinc oxide nanoparticles by the pulsed arc discharge plasma. We also investigated the effect of discharge parameters （frequency, pulse width, current value） on synthesized particles. Synthesized particles were characterized by scanning electron microscopy （SEM）, and X-ray diffraction （XRD）. As a result, it was found that the composition of the zinc oxide nanoparticles was affected by the pulse width and current value. In addition, AZO nanoparticles were synthesized using Zn and Al as electrodes. As a result, gahnite nanoparticles were synthesized instead of AZO nanoparticles. It was suggested that this is related to the temperature of the arc discharge plasma.
