The study was carried out to clear the effects of the only nitrogen discharge luminescence and of the nitrogen discharge luminescence with oxygen silent discharge on ozone synthesis. A coaxial and cylindrical double layer discharge tube was used for ozone synthesis. Nitrogen gas was enclosed in the inner tube, and AC high voltage was applied between the rod electrodes. The oxygen which flowed between the inner and outer tube was irradiated by nitrogen-discharge luminescence, and the amount of ozone was measured.
Next, the inner tube was rolled by nickel mesh as an electrode and the outer tube was rolled by aluminum foil as an another electrode. The silent discharge were generated in oxygen gas and the discharging oxygen gas was exposed by the nitrogen discharge luminescence.
The following results were obtained. The amount of ozone generated by the only nitrogen dischage luminescence was a little. And, the amount of ozone generated by the oxygen silent discharge with the irradiation of nitrogen discharge luminescence was more than in the case with the non-irradiation. This result is due to get the effective discharge condition for ozone synthesis owing to irradiate the nitrogen discharge luminescence.
