P-105: Measurement of Excited Xe Atoms Density in metastable (1S[sub 5]) and resonant (1S[sub 4]) state in Alternating Current Plasma Display Panel by means of Laser Absorption Spectroscopy

Abstract

The exited Xe atoms in the 1s5 metastable state and the 1s4 resonance state across the two sustaining electrode have been monitored in a micro discharge cell of alternating current plasma display panels by laser absorption spectroscopy. In this study, it is found that the maximum excited xenon density is 5.4 × 1012 cm−3 in the 1s5 metastable state and 1.2 × 1012 cm−3 in the 1s4 resonance state for the PDP cell with gap distance of 150 um and width of 350 um under the fixed gas pressure of 350 Torr and a mixture of Xe content ratio of 10 % with Ne under driving frequency of 35 When increasing PDP driving frequency from 35 kHz, 50 kHz up to 100 kHz, it is found that density of excited Xe atom in the 1s5 metastable state increase from 6.5 × 1012 cm−3 up to 1.39 × 1013 cm−3.
