To investigate the dependence of vacuum ultraviolet (VUV) emission from exited Xe＊(1s4)atoms and Xe2＊dimers on gas pressure in a small discharge cell, we constructed anexperimental panel with a horizontal cell pitch of less than half the value of a current AC-PDP.The panel was filled with a mixture of Ne and Xe (5%), and the total gas pressure wasincreased from 40 kPa to 93 kPa. The spatiotemporal behavior of Xe＊(1s5), which affected theVUV band emission, was measured by microscopic laser absorption spectroscopy. The exitedXe＊(1s5) atoms transited to Xe2＊dimers in a short time, thus stronger VUV emissions wereestimated at higher gas pressure. |
