Influence of discharge parameters on the synthesis and properties of nanoparticles in reactive plasmas — •Alexander Schmitz, Andreas Petersen, and Franko Greiner — Institute of Experimental and Applied Physics, Kiel University, Germany

Reactive plasma can be an attractive source for sub-micron particles of several 100 nm size. Such particles are be a candidate for pharmaceutical carriers, catalytic or functional material. The influence of the discharge parameters on the accretion growth process and the nanoparticle properties especially still pose open questions. Their precise determination is not only of importance for fundamental research on particle dynamics and electron depletion processes, but also for potential technical applications.

Modern in-situ diagnostics based on light scattering like full-Stokes imaging polarimetry offer valuable insight into the particle characteristics. It is a door opener for accessible computer vision and precise scattering modeling to access particle properties. We present a first study on the tunability of nanoparticle properties with regard to the particle size distributions, complex refractive index and their spatial dynamics.
