ABSTRACT:
The present invention inhibits water adsorption onto the surface of a blue phosphor, decreases luminance degradation and chromaticity shift of a phosphor, or improves discharge characteristics thereof. The blue phosphor is a compound represented by Ba1-xMgAl10O17:Euxor Ba1-x-ySryMgAl10O17:Eux, wherein 0.03≦x≦0.25 and 0.1≦y≦0.5, and containing at least one of Ti, Zr, Hf, Si, Ge, Sn, and Ce substituting for part of one of elements Al and Mg.
