Study into Synchronous Flows of Bactericidal Ultraviolet Radiation and Transition Oxides Metals (Zn, Cu, Fe) in a Pulsed Gas Discharge Overvoltage Reactor Nanosecond Discharge in the Air

Abstract

The characteristics of an overstressed, high-current nanosecond discharge in atmospheric air between zinc, copper, and iron electrodes are given with a distance between the electrodes of 1–3 mm. It is established that this discharge is a point source of ultraviolet radiation in the spectral range of 200–300 nm and a nanoparticle stream of zinc, copper, and iron oxides. The optimization results of the UV emitter depending on the pumping conditions and parameters of the discharge medium, as well as the optical characteristics of the film nanostructures of transition metal oxides deposited on the surface of a glass substrate, are presented.
