N2 Active Species in DBD Afterglows: Optical Spectroscopy at Atmospheric Pressure
0Density of N2 Active Species in N2 Dielectric Barrier Discharge Afterglows by Optical Spectroscopy at Atmospheric Gas Pressure
Layman's Abstract: Dielectric Barrier Discharges (DBD) are a method used to create Cold Atmospheric Plasmas, specifically nitrogen afterglows, which are glowing gases. These afterglows were studied using light emission in various wavelengths, from ultraviolet (UV) to near-infrared (IR) ranges. Scientists used a model to figure out the amounts of different active nitrogen and oxygen species present in the afterglow. They found that the number of these species decreased slowly over time, with nitrogen atoms, excited nitrogen molecules, and oxygen atoms being the most abundant. Other less abundant excited species were also found but in much smaller amounts.
