Original Abstract
This presented work gives new preliminary results about the influence of other species added into the nitrogen post-discharge. DC nitrogen flowing discharge was created at 1000 Pa in the quartz tube, and the discharge current was adjusted at 150 mA. Selenium hydride was generated on line and it was further dried by a molecular sieve. The hydride was introduced into the nitrogen post-discharge at the decay time of 15 ms using Pyrex capillary oriented from down stream side of the main discharge tube. The plasma was studied by optical emission spectroscopy in the range of 320-780 nm at the fixed post-discharge position of 15 ms decay time. The three nitrogen spectral systems (first and second positive, and first negative) were detected in the spectra, only. Based on the spectra, the relative distributions of nitrogen radiative states were calculated. The strong decrease of population at all vibratiolnal levels was observed. The experimental results show that the main influence of the added selenium hydride is through the changes of Quartz wall properties.
