Generation of atmospheric pressure air diffuse discharge plasma in oxygen enriched working gas with floating electrode

In this work, a floating electrode is employed to generate a stable large-area diffuse discharge plasma under an open oxygen-rich environment. The discharge image and the optical emission spectra of the N₂(C-B),N₂⁺(B-X), N²(B-A), and O(3p–3s, 777 nm) are measured to analyze the morphological and optical characteristics of the discharge. The effects of applied voltage, gas flow rate, and electrode gap on the reactive species, vibrational temperature and...
