Silver nanoparticles synthesis in plasma-liquid secondary microdischarge system

This paper presents results of investigation of atmospheric pressure plasma-liquid interface system with a secondary discharge supported by low-power microdischarge system with vortex Ar flow. Continues flow of working liquid, which were aqueous solutions of silver nitrate, was treated by low-power microdischarge. The microplasma discharge and the secondary discharge were powered by a DC supplies. Treatments of working liquid (with and without polyvinylpyrrolidone) were conducted in air or in an argon atmosphere. The plasma was studied by using emission spectroscopy technique. The working liquid and firm products, created after the treatment, were studied by absorption spectroscopy method and on an atomic force microscope correspondently.
