我们报告了由光谱过滤增强电荷耦合器件（ICCD）相机获得的喷射型介质阻挡放电中的时间分辨图像，其中有两个交叉的气流。 He 和 Ar 气体的交叉流配置以及添加到 Ar 流中的少量丙酮杂质分别模拟了材料加工实际应用中的放电配置和有机前驱体。从 ICCD 图像中，可以区分电极和基底之间的流光放电和瞬态辉光放电。激发态 N2+、CH、C2、He 和 Ar 的过滤发射也揭示了放电中的激发和分解过程。
We report on temporally resolved images in a jet-type dielectric barrier discharge with two crossed gas flows obtained by a spectrally filtered intensified charge-coupled device (ICCD) camera. The crossed-flow configuration of He and Ar gases and a small acetone impurity added into the Ar flow simulated a discharge configuration and an organic precursor used for the practical application of material processing, respectively. From the ICCD images, streamer and transient glow discharges could be distinguished between the electrode and the substrate. Filtered emission from excited N2+, CH, C2, He, and Ar also revealed the excitation and decomposition processes in the discharge.
