Optical diagnostic of air surface dielectric barrier discharge plasma

Surface dielectric barrier discharges (SDBDs) are promising nonthermal plasma systems for industrial-scale operations. These plasmas are scalable, and the plasma operation is relatively unaffected by the characteristics of the target samples. Therefore, these systems are suitable for diverse applications, including surface modification and environmental remediation. However, the accurate diagnostic of the plasma system is crucial for developing an optimal SDBDs plasma system for a specific application. Non- invasive optical emission spectroscopy (OES) is one of the most suitable diagnostic tools for characterizing and optimizing the plasma.
