实验结果表明，在大气压下，利用三电极微阴极持续放电（MCSD）装置可以有效地产生单线态氧O2（aΔ1g）.该配置包括一个微空心阴极放电（MHCD）作为等离子体阴极，以维持稳定的辉光放电之间的MHCD和第三平面电极放置在8 mm的距离。实验中进行He/O2/NO混合物。在MCSD余辉中，在总流量高达30 ln/mn时，测量到高于1016 cm−3的O2（aΔ1g）数密度，导致O2（aΔ1g）通量高于10毫摩尔/小时（mmol/h）。
We report experimental results showing that singlet oxygen O2(aΔ1g) can be efficiently produced at atmospheric pressure in a three-electrode microcathode sustained discharge (MCSD) configuration. This configuration consists of a microhollow cathode discharge (MHCD) acting as a plasma cathode to sustain a stable glow discharge between the MHCD and a third planar electrode placed at a distance of 8 mm. Experiments were performed in He/O2/NO mixtures. O2(aΔ1g) number densities higher than 1016 cm−3 were measured in the MCSD afterglow at total flow rates up to 30 ln/mn, resulting in O2(aΔ1g) fluxes above 10 millimole per hour (mmol/h).
