| Abstract(in English) | Blue PDP phosphor BaMgAl_<10>O_<17>:Eu^<2+> (BAM:Eu^<2+> with β-alumina structure shows the luminance degradation at the panel production and panel operation due to the oxidation of activator and defect-generation in a host crystal. To prevent this luminance degradation, phosphor characteristics of a blue phosphor CaAl_2O_4:Eu^<2+> (CA:Eu^<2+>) with β -tridymite structure were investigated.. The photoluminescence (PL) intensity of CAEu^<2+> (1 % Eu content) prepared by the two-step firing synthesis is about 50% of that of BAM:Eu^<2+> under 147 nm excited light. By baking the phosphors in air at 600 ℃, the PL luminance is decreased to 88 % for CA:Eu^<2+> and to 79 % for BAM:Eu^<2+>. The testing panel using CA:Eu^<2+> phosphor shows the same spectrum of powder phosphor. However the luminance of testing panel with CA:Eu^<2+> is still 35 % of that with commercial BAM;Eu^<2+> phosphor. |
