Analysis of Oxygen Atmospheric Band in Dielectric Barrier Discharge at Atmospheric Pressure
The emission spectra of pure oxygen in dielectric barrier discharge at atmo spheric pressure were observed. Comparison between experimental and fittings pectra of oxygen A band (b 1Σ+g→X 3Σ-g)(0,0)was used to determine the gas temperature,and the electronic temperature was calculated from O Ⅰ lines. The causation of oxygen A band in atmospheric dielectric barrier discharge was discussed by means of analysis of producing and quenching approaches. The result showed that the electronic temperature,(11 800±400) K,was much higher than the gas temperature,(650±20) K. The emission from a 1Δg or A 3Σ+u was not been observed,but atmospheric band with its resoluble rotational structure was measured.
