Light emission and temperatures during the DC afterglow in nitrogen-oxygen mixtures
Original language description
This contribution focuses on the oxygen influence to the pure nitrogen post-discharge. The DC flowing afterglow in Pyrex tube at discharge current of 150 mA and pressure of 1000 Pa was studied by optical emission spectroscopy at decay times in the rangeof 3 ? 45 ms. Band head intensities of 1st and 2nd positive and 1st negative nitrogen spectral systems were observed as a function of oxygen admixture ( 0-5000 ppm). The nitrogen pink afterglow effect was observed in all cases. Temperature during the afterglow was determined by two different ways. The first one was the direct calculation of the rotational temperature of nitrogen 1st positive 2-0 band using numeric simulation. The second way was the strongly temperature-sensitive ratio of band head intensities originating from 11 and 12 vibrational levels of N2 (B 3g) state because these levels were populated during the afterglow mainly by the atomic nitrogen recombination.
