  • Abstract
    Phosphors suitable for a full-color TV display in recently reported new high-luminance (360-fL green) high-efficiency (3.4-lm/W) gas-discharge cells have been determined: blue Sr5Cl(PO4)3Eu+2, green Zn2SiO4:Mn+2, and red Y2O3Eu+3. A decrease in color gamut with increasing current density has been measured and related to gas-discharge effects rather than phosphor saturation, using experimental results and a simplified model calculation. Aging of the green phosphor was measured and its causes are discussed.
