Originální abstrakt

The work presents results obtained during spectroscopic observations of DC flowing post-discharges of pure nitrogen plasma containing traces of oxygen. The plasma has been studied by the emission spectroscopy of three nitrogen spectral systems and NO-beta bands. The maximum of the pink afterglow intensity of nitrogen 1st positive system decreased more or less exponentially with increasing the oxygen concentration. The position of the maximal pink afterglow emission was shifted to shorter decay times but both nitrogen positive systems showed a slow increase of the decay time of pink afterglow maximum after the initial shift to the earlier post-discharge position. Intensities of both nitrogen positive systems didn't show any significant dependence on the oxygen concentration. The NO-beta bands were observed with low intensity and their intensities were directly proportional to the oxygen concentration.
