A highly reliable light-emitting device is provided, which is capable of effectively suppressing detrimental effects of sulfuric gas. A light-emitting device comprising a solid light-emitting element 1, a metal member 2 reacting with sulfuric gas and a phosphor-containing layer 5 that contains a phosphor 3, the phosphor-containing layer 5 containing a sulfuric gas-adsorbing substance 4 that adsorbs sulfuric gas, and, when the phosphor-containing layer 5 is tripartitioned from the side near the metal member to far into a proximal layer portion, an intermediate layer portion and an outer layer portion, the concentration of sulfuric gas-adsorbing substance 4 in the proximal layer portion is made to be higher than those for the intermediate layer portion and the outer layer portion.

A metal back-attached phosphor screen comprises at least a phosphor layer (3) and a metal back layer (5) on an inner surface of a face plate (1), a first treatment layer (4) containing at lest one kind of inorganic oxide such as SiO2,a silicon oxide containing an alkali metal such as Na, Al2O3, TiO2, or ZrO2 formed on the phosphor layer (3), and the metal back layer (5) formed thereon. A second treatment layer containing the aforementioned inorganic oxide can be formed on the metal back layer (5). A metal back-attached phosphor screen, when used in an image display device such as a FED, can not only inhibit the occurrence of abnormal discharge and improve withstand voltage characteristics but also can increase brightness.

A phosphor particle includes a phosphor containing zinc sulfide as a base material, and a coating layer applied on the phosphor and made of a magnesium phosphate expressed by Mg3(PO4)2.
摘要:
Fluorescent material for display unit (1) comprising fluorescent substance matrix particles (2) constituted substantially of zinc sulfide of crystal structure composed mainly of, for example, hexagonal crystal or cubic crystal. First activator (3) is localized in surface layer part (2a) of the fluorescent substance matrix particles (2). Second activator is uniformly dispersed in the fluorescent substance matrix particles (2). The color of light emitted from a fluorescent substance of zinc sulfide having a crystal structure of, for example, hexagonal crystal can be improved by such a particle structure. Alternatively, unwanted light emission attributed to an electron beam on the low voltage side of the fluorescent substance for display unit (1) can be suppressed.
