Schematic diagram of D2O + N2 plasma jet device and its OES spectra (A) A plasma jet system consisting mainly of a high-voltage power supply, electrodes and dielectrics; (B) Shows vacuum chamber consists of vacuum pump which used to take out atmospheric gas from inside the chamber and then chamber was filled with nitrogen gas only; (C) D2O + N2 plasma jet device was used in this experiment. The distance between the cell media and outer electrode is kept as 3 to 4 mm during exposure; (D) Measurement optical emission spectra during treatment with plasma.
