Abstract:
A blue phosphor composing a blue phosphor player in a plasma display device has a crystal structure of Ba(1-x)EuxMgAl10O17 or Ba(1-x-y)EuxSryMgAl10O17. In this blue phosphor, La substitutes for a proportion of Ba or Sr so as to achieve a high-luminance plasma display device with less luminance deterioration in panel manufacturing processes.
