Under a Contract a fundamental, theoretical and experimental investigation of the factors affecting brightness, color and efficiency of ac plasma panel displays was conducted. Initial emphasis in the program was placed on plasma displays using conventional neon-Penning mixtures. An important finding of this portion of the work was that the brightness and efficiency of such displays are limited to present levels by several fundamental factors. The possibility of using visible excimer molecule fluorescence for displays was subsequently explored, with attention focused on rare gas-halide and rare gas-oxide excimers. Theoretical analysis indicating that such molecules had promise for the development of bright alternate color displays was confirmed experimentally with the observation of blue fluorescence from Xe sub 2 Cl and green fluorescence from XeO emanating from display discharges. In both cases the measured luminance was found to be greater than that of a neon-Penning mixture excited under the same conditions. Author
