Originální abstrakt

This work extends our recent investigation of mercury excitation under post-discharge conditions and presents results obtained during spectroscopic observations of mercury titration in nitrogen DC flowing postdischarges. DC discharge in quartz tube was created at 1000 Pa and 290 W. The plasma was studied by optical emission spectroscopy in the range of 300-800 nm. Besides three nitrogen spectral systems (first and second positive and first negative), the mercury line at 254 nm was recorded in the second order spectrum at 508 nm under these conditions. Its intensity was dependent on the mercury vapor flowing. No other mercury lines were observed. The upper state of observed mercury spectral line is 3P1, and it is probably created by the resonance excitation energy transfer from vibrationally excited nitrogen ground state N2 (X 1?g+, v = 19).
