Abstract: front page image
(EN)Provided is a plasma display device having a novel phosphor layer which emits green light and improved initial emission luminance and improved emission luminance maintaining rate. The phosphor layer includes a mixture of particles of Zn2SiO4:Mn and particles of (Y, Gd)BO3:Tb. The surface of the particles of Zn2SiO4:Mn is covered with aluminum oxide. The ratio of Al to Si measured by an X-ray photoelectron spectroscopy (XPS) apparatus on the particle surface is 0.6 or more but not more than 7.0.
(FR)L'invention concerne un écran plasma comprenant une nouvelle couche de phosphore émettant une lumière verte et présentant une luminance d'émission initiale améliorée et un taux de maintien de luminance d'émission amélioré. La couche de phosphore comprend un mélange de particules de Zn2SiO4:Mn et de particules de (Y, Gd)BO3:Tb. La surface des particules de Zn2SiO4:Mn est recouverte d'oxyde d'aluminium. Le rapport entre l'Al et le Si, mesuré au moyen d'un appareil de spectroscopie photoélectronique à rayonnement X (XPS) sur la surface des particules, est supérieur ou égal à 0,6 mais ne dépasse pas 7,0.
