Originální abstrakt

This work extends our recent investigation of mercury excitation under postdischarge conditions and presents results obtained during spectroscopic observations of mercury titration in nitrogen DC flowing post-discharges. DC discharge in quartz tube was created at 1 000 Pa and 290 W. The plasma was studied by optical emission spectroscopy in the range of 300-800 nm and 248-260 nm, respectively. Three nitrogen spectral systems and mercury spectral line at 254 nm were identified. The results showed dependence of mercury spectral line maximal intensity on the decay time. The kinetic explanation can be made through a strong depopulation of the level N2 (X,, v = 19) creating the mercury 3P1 state that is upper state of mercury UV line at 254 nm. The numeric model was used for the comparison of proposed kinetic processes to the experimental data.
