本文首次报道了一种在平面介质管道中产生的含氧氩等离子体射流，该射流的一端附着在介质平面上，然后进入大气。这种氩氧等离子体射流可以在低电压下作为大气压下的辅助放电工作。少量氧气的加入导致产生的臭氧浓度增加，并且以约185 nm、205 nm、230 nm和253 nm为中心的连续发射。短波长紫外辐射和活性物质的协同产生对于等离子体应用是非常重要的。
A nonequilibrium argon plasma jet with oxygen addition, generated in a planar dielectric duct and issuing into ambient air with one edge stuck on a dielectric plane, is reported for the first time. This argon-oxygen plasma jet can be operated at low applied voltage as a filamentary discharge at atmospheric pressure. The addition of a small amount of oxygen results in the increase of produced ozone concentration and continuous emissions of centering at about 185 nm, 205 nm, 230 nm, and 253 nm. The synergistic generation of short wavelength ultraviolet emissions and active species is significantly important for plasma applications.
