    Abstract:
    The electron energy in the transition from streamer discharge to glow-like discharge in dielectric barrier discharge in air was investigated by using emission spectra. The vibrational temperature was measured with the N2 second positive band (C3II(u) --> B3II(g)) of the emission spectrum. The average electron energy was investigated from the relative intensity of the nitrogen molecular ion line at 391.4 nm and the nitrogen molecular line at 337.1 nm. It was found that the vibrational temperature and the relative intensity of nitrogen molecular ion line at 391.4 nm increased abruptly in the transition from streamer discharge to glow-like discharge. It was also found that the pressure for the transition pressure from streamer discharge to glow-like discharge changed with different gap distances, but the product of the transition pressure and gas gap width remained constant.
