对ZnO涂层表面阻挡放电的特性进行了光学诊断。在电介质表面沉积了高导电性的ZnO薄膜。我们发现，表面电导率的增加诱导更宽的放电区域。此外，我们还利用发射光谱分析了两种阻挡放电等离子体跃迁的光学行为。普通介质阻挡放电的放电特性仅分为两种模式：流光放电和辉光放电。而在ZnO涂层介质阻挡放电中，类辉光放电的局部放电范围较宽，这也是提高等离子体均匀性的一个证据。
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.
