    摘要： Panel including a transparent front plate and a rear plate that leave between them discharge spaces, the walls of which are at least partly coated with a layer of a phosphor capable of emitting green, blue or red light; the green phosphor is formed from a mixture of two aluminates having a spinel structure, one A doped with manganese and the other B doped with cerium and with terbium; preferably, the blue phosphor is based on an aluminate of the same structure. The static charges of the various phosphors are homogenized and the risks of phosphor performance degradation during manufacture of the panel are limited.

    摘要： A plasma display panel. A pair of substrates has a transparent front surface and is disposed to leave a discharge space therebetween. A plurality of barrier ribs is disposed on one substrate to partition the discharge space into a plurality of respective green discharge spaces, blue discharge spaces and red discharge spaces. A group of electrodes is disposed on the substrates to discharge in the discharge spaces partitioned by the barrier ribs. A phosphor layer is formed in the discharge spaces, the phosphor layer being a green phosphor layer for the green discharge spaces, a blue phosphor layer for the blue phosphor discharge spaces, and a red phosphor layer for the red discharge spaces. A discharge gas is filled in the discharge spaces, wherein the green phosphor layer comprises from 10 to 70% by weight of a first green phosphor selected from the group consisting of Zn2SiO4:Mn, (Zn, A)2SiO4;Mn (where A is an alkali metal), and mixtures thereof; from 0 to 30% by weight of a second green phosphor selected from the group consisting of (Ba, Sr, Mg)O.aAl2O3:Mn (where a is from 1 to 23), LaMgAlxOy:Tb,Mn (where x is from 1 to 14 and y is from 8 to 47), and mixtures thereof; and from 20 to 70% by weight of a third green phosphor selected from the group consisting of ReBO3:Tb (where Re is at least one rare earth element selected from the group consisting of Sc, Y, La, Ce, and Gd), and wherein the discharge gas comprises at least 6% by weight of Xe based on the total weight of the discharge gas.
