Abstract

The paper presents the comparative results concerning the excimer intensity radiation emitted by xenon-iodine/chlorine gas mixtures with and without buffer-gases, namely Ar, He and Ne, in a dielectric barrier discharge at moderate pressure (20-40Torr). It was established the optimum for the total pressure of the gas mixture vs. the emitted radiation intensity. Changes appear in the presence of the buffer-gases. The optimal iodine/chlorine pressure range was investigated and also the linear increase of UV power vs. Xe pressure.
