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. Used in a phosphor for a plasma display is a blue phosphor in which trivalent Eu ions substitute for part of divalent Eu ions. This substitution eliminates oxygen vacancy in the vicinity of layers containing Ba atoms (Ba-O layers) in the blue phosphor, and thus inhibits water adsorption onto the surface of the blue phosphor, decreases luminance degradation and chromaticity shift of the phosphor, or improves discharge characteristics thereof. <IMAGE> |
