Excimer lamps dielectric-barrier discharge

An excimer lamp has dual quartz-tube structure, where a metal electrode is set at the inner side of the inner tube, and a mesh-type metal electrode is placed at the outside of the outer tube as shown in Fig. 5. When we apply ac high voltage between two electrodes, the dielectric barrier discharge ignites between two dielectric materials, and reaches an excimer state instantaneously by the excitation of atoms of a filling gas. Then the excimer light is emitted by the... 

The incoherent excimer radiation from a dielectric barrier discharge (silent discharge), operating in pure xenon, gas mixtures of krypton/chlorine, and xenon/chlorine, provides intense narrow-band radiation. More details about the excimer UV sources can be found in the literature [236, 237]. As irradiation sources a XeCl (308 nm), a KrCl (222 nm), and a Xe2 (172 nm) excimer lamp were selected. Excimer lamps based on fluorine-containing excimers are difficult to operate, due to etching of the quartz housing by the F2.
