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.

摘要:
A method of manufacturing a plasma display device which prevents the brightness of a phosphor layer from lowering is disclosed, and the method can form the phosphor layer in a stable manner because a nozzle is free from clogging. At least one of the phosphor layers has a green phosphor layer containing green phosphor having zero or positive charges and a crystal structure of Zn2SiO4:Mn. Green phosphor ink, whose major ingredient is the green phosphor, is applied through the nozzle to discharging cells, thereby forming the green phosphor layer. The green phosphor ink is formed of green phosphor powder coated with an oxide having positive charges, or the ink is formed by crushing the green phosphor powder originally having negative charges and a crystal structure of Zn2SiO4:Mn such that the powder changes to have positive charges.
