Description	A dc excited discharge generated in bubbles (He, Ar, Air, N2) in liquid phase is investigated in this work. Voltage/current characteristics and emission spectra of the discharge are recorded in the current range 10-30 mA. Electron density in the discharge is measured from the Stark broadening of H-beta line and it is in the order of 2-6 x 1020 m-3 depending on the feed gas. Estimation of electron temperature is carried out based on the balance of charged particles. Gas temperature is estimated by the slope of the Boltzmann plot and by the simulation of OH band with different T 1 rot , T 2 rot and Tvib. Rotation temperature in the He discharge is 1200K at I = 10mA and linearly increases up to 1600K with growth of current. In the plasma of molecular gases the temperature is higher and almost constant at different currents. Chemical efficiency of the plasma is measured by the production of H2O2 and by the destruction of Direct Blue 106. The highest energy consumption of H2O2 generation is achieved in the A dc excited discharge generated in bubbles (He, Ar, Air, N2) in liquid phase is investigated in this work.
