摘要

The electron swarm parameters of Xe/He and Xe/Ne mixtures are analysed with a Boltzmann equation method in which secondary generations of electrons through excited atoms are properly considered. The swarm parameters are examined for a wide range of the electron concentrations from the Townsend discharge region to thr: working condition of plasma display panels (PDPs). Using ionization coefficients obtained in this work and referred values of secondary electron emission coefficients from MgO film, the discharge onset voltage V-b is discussed. The Paschen curves around (p(0)d)(min) at which V-b has a minimum are compared for Xe/He and Xe/Ne mixtures. Under the working conditions for PDP discharges, the radiation rates of ultraviolet light (lambda = 130, 147 and 173 nm) from the Xe resonance levels and Xe excimer are calculated. A suitable discharge condition for designing PDP is discussed with respect to various values of the gas mixture ratio, gas pressure and reduced electric field. [References: 47]
