Relationships between the energy density and plasma-induced electrons and reactive species. (a) Calculated mean electron energy and electron density as a function of discharge power. (b) Scheme of the ternary relationship among the SEI (corresponding to the discharge power), relative intensity of Ar atomic line at 763.51 nm from OES, and calculated rate constants of Ar* formation reactions. (c) Calculated EEDF under different reduced electric fields E/N. (d) Energy fraction consumed in different electron-impact reactions of Ar as a function of the reduced electric field E/N (green zone illustrates the range of operating conditions in this study). NTP system: Ar flow rate 100 mL/min; anisole feed rate 3.0 mL/h.
