| Description | Diffuse Coplanar Surface Barrier Discharge (DCSBD) is a novel type of atmospheric-pressure plasma source developed for high-speed large-area surface plasma treatments. Basic characteristics of DCSBD burning in pure atmospheric-pressure hydrogen were measured using optical and emission spectroscopy methods, and its potential for the surface treatment application was demonstrated by hydrogen plasma reduction of Cu2O thin layers. The discharge generates a thin layer of diffuse non-equilibrium plasma with a high power density of 75W.cm^-3 . The mean electron density and electron temperature derived by the spectroscopy data were 1.3x10^16 cm^-3 and 19x10^3 K, and the surface Cu2O layers forming a weak boundary were reduced to metallic copper within several seconds. |
