Effect of Reactive Gas Dopants on the MgO Surface in AC Plasma Display Panels

Experimental results are presented for the influence of controlled levels of important reactive impurities (N2, O2, H2O, CO2) on the aging characteristics of the operating voltages of ac plasma display panels. Details are also given of a novel method of modifying the electronic properties of MgO surfaces by discharge processing in an oxygen-doped Ne-0.1% Ar Penning mixture.
