Description
  • The DC flowing post-discharge in nitrogen containing mercury traces of about 3.14 ppb was studied in Pyrex tube by emission spectroscopy. The relative populations of N_2 (B ^3 Pi_g), N_2 (C ^3 Pi_u) and N_2^+ (B ^2 Sigma_u^+) states were calculated in the dependence on the post-discharge time in the range of 3 - 40 ms. As the uncontrolled oxygen traces were recorded in the mercury flow the experiment with nitrogen-oxygen mixture was added. The results showed strong quenching of the nitrogen pink afterglow by mercury traces. The kinetic explanation should be done through strong depopulation of level N_2 (X ^1_g^+, v = 20) (creation of mercury ^3 P_1 state) and levels N_2 (X ^1 Sigma_g^+,v = 28) or N_2 (A ^3 Sigma_u^+,v = 4) (creation of mercury ^1 S_0 state). Both mercury states are origins of UV light emission (254, resp. 185 nm) that could not be detected in our experimental set up.

  • Stejnosměrný průtočný dohasínající výboj v dusíku obsahujícím příměsi rtuti v množství okolo 3,14 ppb byl studován v pyrexové trubici pomocí emisní spektroskopie. Relativní populace stavů N_2 (B 3^Pi_g), N_2 (C ^3 Pi_u) a N_2^+ (B ^2 Sigma_u^+) byly počítány v závislosti na čase dohasínajícího výboje v rozmezí 3 až 40 ms. Protože v proudu rtuti byly zaznamenány neřízené příměsi kyslíku, ke studiu byl přidán experiment se směsí dusík-kyslík. Výsledky ukázaly, že růžový dosvit dusíku je silně zhášen stopami rtuti. Kinetické vysvětlení by mělo být v silném snížení populace hladiny N_2 (X ^1 Sigma_g^+,v = 20) (tvorba stavu rtuti ^3 P_1) a hladin N_2 (X ^1Sigma_g^+,v = 28) nebo N_2 (A ^3 Sigma_u^+,v = 4) (tvorba stavu rtuti ^1 S_0). Oba stavy rtuti jsou zdrojem emise UV záření (254, respektive 185 nm), které však nemohlo být v našem experimentálním zařízené detekováno. (cs)
