Optical emission spectroscopy of atmospheric-pressure non-equilibrium plasma with mist injection

Optical emission spectroscopy of atmospheric-pressure non-equilibrium plasma with mist injection

This paper describes optical emission spectroscopic diagnostics of atmospheric-pressure non-equilibrium plasma with mist injection. Electron number densities and gas temperatures are estimated from Hβ (486 nm) and OH (309 nm) spectra to be on the order of 1015 cm-3 and 440–540 K, respectively, for t...
