| Abstract(in English) | BaMgAl_10O_17: Eu^<2+>(BAM: Eu^<2+>) is currently used for a plasma display panel (PDP) blue phosphor. However the intensity of blue emission is decreased by the thermal treatment for the panel production and by VUV irradiation and ion bombardment for driving the panels. We propose a blue PDP phosphor CaAl_2O_4: Eu^<2+> (CA:Eu^<2+>) which is thought to be chemically stable than BAM:Eu^<2+>. CA: Eu^<2+> phosphor shows a pure blue emission under 147 nm excitation. The photoluminescence (PL) intensity of CA:Eu^<2+> is about 12% of that of BAM: Eu^<2+>. After annealing at 600℃, the PL luminance of CA: Eu^<2+> can be kept at 93%, of the initial luminance. |
