Abstract

AbstractThe vacuum ultra‐violet (VUV) ray emission characteristics for Plasma Display Panels (PDP) were studied using various 3‐component (He‐Ne‐Xe) gas compositions and 2‐component (He‐Xe, and Ne‐Xe) systems.In the 3‐component (Xe‐25%Ne‐He bal.) systems, an increase in the pressure and Xe content contributed to an increase in the 147nm atomic emission, whereas above a certain point this decreased. In contrast, in the 2‐component 4%Xe‐Ne bal. System, the 147 nm atomic emission was saturated with an increase in pressure. Integrated intensities of 147nm, 172nm and the total were largely changed with different measuring conditions (Vfixed and Vsus), with Xe content variation. With the increase of Xe content, when measured at Vsus, atomic emission shows maximum value at 8 % while dimer emission linearly increased. On the other hand, atomic emission shows maximum value at 4 % in Vfixed condition. Different 3‐component gas compositions with the same Xe partial pressure showed nearly the same optical properties at a fixed applied voltage. In the case of Ne, the 147nm peak increased and the 172nm peak decreased with an increasing Ne content.
