Abstract: | This paper presents surface dielectric barrier discharge plasma generators as an efficient source of low-energy ions. Either positive or negative ions can be extracted from a plasma cloud with an external DC field created by the third electrode. Three different cross-section geometries of DBD generators were analyzed, simulated and fabricated. Currents of ions extracted from the plasma cloud were measured and the results were discussed. It was demonstrated that if the third electrode consists of liquid–gas interface, the presented arrangement can be used as a versatile reactor for nanomaterial synthesis (on the example of the synthesis of silver nanoparticles). |
