PLASMA DISPLAY APPARATUS, FLUORESCENT MATERIAL, AND FLUORESCENT MATERIAL MANUFACTURING METHOD

摘要

The present invention aims to inhibit water adsorption onto the surface of a blue phosphor(blue fluorescent material), decrease luminance degradation and chromaticity shift of a phosphor, or improve discharge characteristics thereof. In a phosphor layer used for a plasma display, elimination of oxygen vacancy in the vicinity of a layers containing Ba atoms (Ba-O layers) in a blue phosphor inhibits water adsorption onto the surface of the blue phosphor, decreases luminance degradation and chromaticity shift of a phosphor, or improves discharge characteristics thereof. <IMAGE>
