Mw. Wright et al., ELECTRODE EFFECTS IN ULTRAVIOLET PREIONIZED BREAKDOWN OF HN3 VERSUS MICROWAVE EXCITATION, Journal of applied physics, 73(11), 1993, pp. 7975-7977
Distinct differences in the emission spectra from the breakdown of HN3
are observed for transverse excitation of HN3 gas mixtures by ultravi
olet (UV) preionization relative to pulsed microwave discharges. In th
e dc UV preionized discharges, electrode effects liberate metal atoms
dominating the emission spectra while the NH(A-X) band emission is abs
ent. Pulsed microwave excitation incorporating an electrodeless quartz
discharge region produces the NH(A-X) emission but reduced by signifi
cant quenching.
