Light Emission and Temperatures During the DC Afterglow in Nitrogen-Oxygen Mixtures

Popis výsledku v původním jazyce

This contribution presents results obtained during the wide study focused on the oxygen influence to the pure nitrogen post-discharge. The DC flowing afterglow in Pyrex tube (i.d. 13 mm) at discharge current of 150 mA and pressure of 1000 Pa was studiedby optical emission spectroscopy at decay times in the range of 3 - 45 ms. Many band head intensities of 1st and 2nd positive and 1st negative nitrogen spectral systems were observed as a function of oxygen concentration in the wide range from 0 up to 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 of this spectral band. The second way was the use of the ratio of band head intensities originating from 11 and 12 vibrational levels of N_2 (B ^3 Pi_g) state because these levels were populated during the afterglow mainl
