Abstract

Characteristics of the ZnO-coated surface barrier discharge in open air were diagnosed optically. Highly conductive ZnO film was deposited on the dielectric surface. We found that the increase of the surface conductivity induces wider discharge area. Moreover we analyzed the optical behavior of plasma transition of two barrier discharges by optical emission spectroscopy. Discharge characteristic of the normal dielectric barrier discharge is divided into only two modes: streamer and glow discharge. But in the case of ZnO-coated dielectric barrier discharge, pd range of glowlike discharge exists widely and this can be also an evidence of the enhancement of plasma uniformity.
