Abstract:The emission spectrum line shift and vibrational temperature of dot and line discharges,which coexist in argon/air dielectric barrier discharge, were measured and compared. Emission spectral lines of ArI (2P2→1S5)and the N2 second positive band system (C3Πu→B3Πg) were used to measure the spectrum line shift and the vibrational temperature respectively. It was found that the spectrum line shift of the dot discharge channel is larger than that of the line discharge channel, indicating that the former has high electron density compared to the latter. While the vibrational temperature of the dot discharge channel is lower than that of the line discharge channel.
