Abstract
We report nanosecond time-resolved measurements of the vacuum ultraviolet (VUV) emission and current waveforms for a planar, surface-discharge plasma display electrode in Xe/Ne mixtures. The 173 nm excimer emission is separately resolved from the overall VUV emission by a removable fused silica filter. The time difference between the maximum of excimer emission and that of resonant atomic emission is measured at high Xe concentration. The decay time of the overall VUV emission decreases strongly as the Xe concentration increases due to three-body collisions leading to Xe2 formation. The decay time constants versus Xe concentration and pressure are measured and compared with published rate constants. The efficiency of VUV emission increases rapidly from 4% to 10% Xe, but only marginally with further increase to 30% Xe. For fixed Xe ratio, the VUV emission efficiency drops with increasing driving voltage.
