Influence of plasma decay on emission of 147-nm ultraviolet light from discharge cells in the plasma display panel

The time profile of 147-nm light emission from a cell discharge of the plasma display panel is investigated in terms of the xenon mole fraction χ and the gas pressure p, including the important influences of the diffusion loss of the plasma and the three-body collisions of excited xenon atoms in the resonance state. The light emission profile dY∕dt in time is analytically expressed in terms of the gas pressure and xenon mole fraction. The theoretical analysis indicates that the emission intensity increases from zero, reaches its peak, and then decreases, as time goes by. The peak emission intensity (dY∕dt)p and the corresponding emission time tp are obtained analytically in terms of the gas pressure p and xenon mole fraction χ. The total emission Y of 147-nm light during each discharge in the cells is proportional to the plasma decay time τ. The experimental data are remarkably consistent with the theoretical predictions.
