Experimental results on the dependence of the discharge emission intensity (DEI) on the current in ambient air and argon media for various values of the gas discharge gap dg (45–250 μm) and residual pressure pg (5.33–101 kPa) in a gas discharge system with a dielectric zeolite electrode (ZGDS) are presented for the first time. The unique electronic properties of the microporous surface of the zeolite used in the ZGDS could significantly enhance the emission of electrons from its surface, thereby reducing the ignition voltage Uign. The ignition voltage Uign and the DEI of the ZGDS are found to depend significantly on the electrooptical parameters of the microporous zeolite as well as dg, pg, and the gaseous medium. We therefore believe that a ZGDS with a dielectric microporous zeolite electrode is very promising as a source of cold nonequilibrium plasma at atmospheric pressure (AP) and could be used to create plasma-chemical sources that activate the gaseous medium and surfaces of various materials at AP.
