This work presents a new technique to produce nanoparticles in a controlled manor using highly ionized plasmas that will ionize the source material . The advantage of ionizing the source material is that it will increase the trapping onto negatively charged nanoparticles (NPs) that should result in a significant increase in productivity. In this work we have performed both simulations and experiments. The experiments were performed using high power impulses to generate high plasma densities. The dense plasma yields a high degree of ionization of the sputtered metal species. Solid metal cylinders of Cu, Ag, Ti and Mo were used as hollow cathodes for the synthesis of NPs. By tuning the process parameters, pulsing energy, pulsing frequency, etc., the particle size can range from of 5 nm to 700 nm in diameter.
