Electrical Approach of Homogenous High Pressure Ne/Xe/HCl Dielectric Barrier Discharge for XeCl (308 nm) Lamp

Plasma Chemistry and Plasma Processing (Impact Factor: 2.06). 10/2011; 31(5):787-798. DOI: 10.1007/s11090-011-9305-4

ABSTRACT

This paper reports the investigation of the excimer UV emission efficiency in Ne/Xe/HCl mixture in terms of the homogenous
model of a dielectric barrier discharge. The computer model developed is based on the Ne/Xe/HCl gas mixture chemistry, the
circuit and the Boltzmann equations. The effects of operating voltage, HCl concentration in the mixture as well as gas pressure
on the discharge efficiency and the 172, and 308nm photon generation, under typical experimental operating conditions, have
been investigated and discussed. Calculations suggest that the overall conversion efficiency from electrical energy to VUV
emission in the lamp is greater than 27%, and it will be very affected at high voltage amplitude and high gas pressure with
a significant dependence on the HCl concentration in the gas mixture.

    ABSTRACT: This paper reports the study of the Kr–Cl2 plasma chemistry in terms of the homogenous model of a dielectric barrier discharge and for two kinds of the applied voltage excitation shape. The effect of Cl2 concentration in the gas mixture, as well as gas pressure and power frequency on the discharge efficiency and the 222 nm photon generation, under typical experimental operating conditions, have been investigated and discussed. Calculations suggest that the overall conversion efficiency from electrical energy to ultraviolet emission in the lamp is in the range of 4.4–12 %, and it will be very affected at high chlorine percentage (>1 %) and high gas pressure (>200 Torr). A comparison between the sinusoidal and the burst excitation waveforms reveals that the burst excitation method provides an enhanced light source performance compared to the sinusoidal wave.

    ABSTRACT: We discuss new features of the XeCl*-laser kinetics by using a detailed analysis of the results of complex computer models. In particular, we consider the development of a high scale instability in a XeCl*-laser discharge. The emphasis is made on fundamental problems, mainly on the limitation of the macroscopic approach to the study of such strongly nonequilibrium systems. The results obtained indicate especially the discharge proprieties at the plasma centre.

    ABSTRACT: Narrowband UV and VUV excimer radiation can be generated in a variety of nonequilibrium gas discharges: dielectric barrier discharges, microhollow cathode discharges, arrays of microplasmas, corona discharges. Excimer lamps (excilamps) are now available for a large number of wavelengths and in various geometrical shapes. The availability of nearly monochromatic photon fluxes ranging in energy up to 15 eV resulted in a number of innovative photo-induced processes in photophysics, photochemistry and photobiology. This report focuses on progress made in the last decade.
