The effects of D2 addition on the discharge characteristics of He-Ne-Xe gas mixture in an AC-PDP

In this work, the effects of addition of D2 (Deuterium) in He(70%)-Ne(27%)-Xe(3%) gas mixture on the discharge characteristics were investigated at the pressure of 200 Torr. When the concentration of D2 in He-Ne-Xe gas mixture was varied from 0 to 0.5%, we measured the firing voltage, the sustain voltage, the luminance, the luminous efficiency and the wall charge according to amount of D2, respectively. In the case of a small addition of D2, we have experimentally investigated that the increase of electron due to Penning effect improves an increase of Xe* and Xe2* that emits 147 and 173 nm photons. As a result, when the small addition of D2 in He-Ne-Xe gas mixture, the firing voltage decreased by 9.8%, the sustain voltage decreased by 4.9%, the luminance increased by 19-44%, the luminous efficiency increased by 20-44% and the wall charge increased by 34-45%.
