Abstract

In this work, the effect of the Xe partial pressure on the excimer vacuum ultraviolet (VUV) emission intensity of the plasma display panels is investigated, both by measuring the spectral emission directly and by two-dimensional simulations. Experimentally, we find that at the high Xe partial pressure levels, there is an supra-linear increase of excimer VUV radiation and that determines the strong increase of luminance at the high pressures and high voltage. Due to the increase of the luminance and the almost unchanged discharge current, the luminous efficacy strongly increases with the Xe partial pressure. In addition, we also investigated the dynamics of the VUV generation, by measuring the decay time of the excimer VUV light as a function of the gas pressure. It is found that the decay time decreases with the increase of gas pressure. The spatial characteristics of the excimer VUV emission are also discussed. Different from the Ne and near-infrared emission, the excimer VUV emission is generated near the surface of the electrodes and increases uniformly on both sides of the anode and cathode (i.e., the bulk plasma region). Most importantly, it is found that the VUV production occurs during the afterglow period, while it is almostmore »« less

From the simulations, it can be seen that the Xe{sub 2}*({sup 3}{Sigma}{sub u}{sup +}) excimer species, which are generated from Xe*(1s{sub 5}), play a dominant role in the excimer VUV emission output at the high Xe partial pressure. The two-dimensional simulations also show that the strong increase of Xe excimer excitation states in the case of high pressure is mainly the result of the high conversion efficiency of the Xe excimer states, especially in the afterglow period. Due to the high conversion efficiency of Xe excitation species to Xe excimer species by the high collision rate in the case of high pressure, there is a strong increase of excimer VUV production, especially from the cathode.},

Vacuum ultra-violet emission of plasma discharges with high Xe partial pressure using a cathode protective layer with high secondary electron emission

Journal Article Zhu, Di; Song, Le; Zhang, Xiong; ... - Journal of Applied Physics

In this work, the mechanism of the vacuum ultra-violet (VUV) emission of plasma discharges, with high Xe partial pressure and high ion-induced secondary electrons emission protective layer, is studied by measuring the VUV light emission directly and comparing it with two-dimensional simulations. From the panel measurement, we find that the high intensity of excimer VUV mainly contributes to the high luminous efficacy of SrCaO-plasma display panels (PDP) at a low sustain voltage. The unchanged Xe excitation efficiency indicates that the electron temperature is not decreased by the high secondary electrons emission protective layer, even though the sustain voltage is muchmore »« less

Effect of high Xe-concentration in a plasma display panel with a SrCaO cold cathode

Journal Article Uchida, Giichiro; Kajiyama, Hiroshi; Shinoda, Tsutae; ... - Journal of Applied Physics

We present here measurements of high Xe-contents plasma display panel (PDP) with SrCaO cold cathode. Luminous efficacy ({eta}) shows a two-step increase with Xe-concentration in Ne/Xe gas mixture: {eta} drastically increases up to Xe-concentration of 30% (Xe: 30%), and then attains 5 lm/W at the highest Xe-concentration of Xe: 100%. The high performance PDP with Xe: 100% can be operated at low applied voltage between 230 and 377 V due to the high secondary electron emission from the SrCaO cathode. Emission measurements clearly show the change in discharge characteristics at Xe: 30%, where the discharge changes from a Ne/Xe mixturemore »« less

Influence of gas pressure and applied voltage on Xe excimer radiation from a micro dielectric barrier discharge for plasma display panel

Journal Article Uchida, Giichiro; Kajiyama, Hiroshi; Shinoda, Tsutae; ... - Journal of Applied Physics

We present the influence of gas pressure and applied voltage on Xe excimer radiation from a microdielectric barrier discharge (micro-DBD) in Ne/Xe gas mixture for plasma display panel. Measurements show that the excimer radiation with the 172 nm band lines is strongly observed in the afterglow, and drastically increases with an increase in gas pressure and applied voltage. It is also found that for high gas pressure and low voltage, excimer molecule (Xe{sub 2}{sup *}) is efficiently produced because of less infrared emission from Xe excited atom. The reaction processes of Xe metastable atom (Xe{sub 1s5}{sup *}), which is amore »« less

Study of the first pulse of Ne-Xe-HCl dielectric barrier discharge for the excimer lamp

Journal Article Belasri, A; Bendella, S; Baba-Hamed, T - Physics of Plasmas

A global one-dimensional model of a dielectric barrier discharge which includes the sheath region and the positive column was developed. The model was used to study the electrical properties under operating conditions of the vacuum ultraviolet excimer lamp and to understand the basic processes of plasma kinetics. A 0.5 cm interelectrode gap distance is filled with a Ne-Xe-HCl mixture. Time variations of the charged particles and excited species in the positive column were described. Then the one-dimensional model was used in the cathode region to illustrate (i) the spatio-temporal behavior of electronic and ionic densities and the electric field, andmore »« less

Numerical simulation of discharge structures in Ar/Cs nonequilibrium plasma MHD generator

Conference Okubo, M; Kabashima, S; Okuno, Y; ...

As reported in previous papers, the quasi-one-dimensional simulation code has come to predict almost satisfactorily the performance of the shock tube driven disk MHD generator using cesium seeded argon plasma as working fluid. However, the agreement between experimental and predicted performances was not so good on the conditions that the external load resistance was small, the seed fraction was high or the stagnation pressure was low. On these conditions, it was observed that ionization instabilities occur in the MHD channel. On the other hand, high-speed photographs of the nonequilibrium plasma discharge in the MHD generator were taken on several workingmore »« less
