Paper Abstract

A dielectric barrier discharge system is specially designed with two liquid electrodes and a corresponding photoelectricity detection system. The detection system is composed of lens, apertures, multiplier-tube, digital camera, and an oscilloscope. A rich variety of emission patterns are obtained in the system as the voltage is increased. The wavelength characteristic of the emission patterns in dielectric barrier discharge is investigated. It is found that the wavelength of the emission patterns displays a non-monotonic variation as the applied voltage is increased. When the applied voltage is relatively low, the wavelength of the emission patterns decreases as the applied voltage increases. When the applied voltage is increased over a critical value, the wavelength of the patterns becomes larger as the voltage is increased. The wavelength of the emission pattern may maintain approximately invariable when the voltage is increased within some particular voltage range.
