Particle Size and Pore Structure Characterization of Silver Nanoparticles Prepared by Confined Arc Plasma

Particle Size and Pore Structure Characterization of Silver Nanoparticles Prepared by Confined Arc Plasma

In the protecting inert gas, silver nanoparticles were successfully prepared by confined arc plasma method. The particle size, microstructure, and morphology of the particles by this process were characterized via X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and the corresp...
