“…A thermodynamic analysis in [6] designates that the reaction (4) is higher in terms of being energy-profitable than reaction (3). So, the lifetime of Cl-containing CD-excilamps is restricted by the mechanism (4).…”

“…Just as in electrodeless gas discharge devices it is possible to reach a non-classical CD containing many microdischarges (filaments), random in volume among dielectrics, by discharge gap reduced to 1-10 mm and pressure above 100 Torr, at excitation frequency of tens to hundreds of kilohertz. Such devices became known in the literature as the devices of dielectric barrier discharge (DBD) [3,4]. In DBD, the typical values of electric field strength are 0.1-100 kV cm −2 , and electron density of a single filament could reach 10 14 -10 15 cm −3 .…”

Simple-geometry exciplex lamps of a novel type excited by a capacitive discharge (CD-excilamps) have been investigated. An efficient radiation has been obtained on KrBr*, KrCl*, XeBr*, XeCl* molecules and I* atom. The highest values of efficiency of various working molecules are approximately 10–18%. The lifetime of the operating gas mixture in KrCl*, XeCl*, I* and XeBr* exciplex lamps excited by a CD is above 1000 h. Owing to the above-mentioned characteristics, the exciplex lamps excited by a CD are supposed to be very promising for various applications.

The results of investigations of dielectric barrier discharges parameters and UV-emission of Xe/SF 6 (50:1) mixture related to the pressure and the distance between electrodes are presented. The basic source of UV-emission in Xe/SF 6 mixture is XeF * excimer, whose emission band center is positioned at 354 nm. The mixture pressure was varied in the range from 40 to 180 Torr, and the distance between electrodes changed in range from 3 to 11 mm. The distance between the electrodes and the gas pressure were selected out so that pd-product should be constant. The experiments conducted display that for pd = const in the pressure range of 70-180 Torr there are some regularities which are partly similar to the scaling laws of gas discharge, namely: the current density const; the power dissipated by the discharge 1/p 0.3 ; UVemission power 1/p; the efficiency of lamp 1/p 0.8 ; the current pulse duration 1/p 0.3 . The highest efficiency (6-8%) was reached for 30-50 Torr gas pressure.
