PHOSPHOR FOR FIELD EMISSION DISPLAY AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: A phosphor and a method for producing the same are provided to achieve improved luminous efficiency and performance of the field emission display, while reducing costs and allowing for a mass production. CONSTITUTION: A phosphor is composed of Ga2O3 1 mole, GeO2 0.001 to 0.1 mole, Li2O 0.01 to 0.1 mole and MnO 0.001 to 0.01 mole with respect to ZnO 1 mole. A method for producing a phosphor comprises the steps of mixing ZnO, Ga2O3, GeO2, Li2O and MnO compound; performing a vacuum evacuation on the mixed compound; baking the vacuum evacuated compound for 9 to 12 hours at the temperature of 900 to 1200 Deg.C; cooling the baked compound; and classifying the cooled compound.
