Abstract: The present invention is characterized by a DC-driven inorganic EL element useful for mobile and other applications, the EL element including at least plural electrode layers, and a light emitter layer made of an inorganic composition, which is provided between the electrode layers, wherein the attainted brightness in the DC drive is 10000 cd/m2 or more.

Abstract: The present invention relates to an inorganic composition mainly containing a compound semiconductor, wherein the inorganic composition contains iridium element. The invention also relates to a method of producing an inorganic composite for producing an luminescent material, wherein the method comprises subjecting an inorganic composition mainly containing a compound semiconductor to an explosion by gunpowder and/or explosive in a sealed vessel. An inorganic composite for producing a luminescent material can be prepared by subjecting an inorganic composition to a doping treatment such as explosive treatment or heat-treatment. The inorganic composite can further be heat-treated to produce a luminescent material. The resulting luminescent material can be formed into a layer as a light emitter layer of an inorganic EL device.

Abstract: In a high luminance, long-life luminous body, a method for manufacturing the luminous body, and a light-emitting apparatus according to the present invention, an inorganic EL device, which is formed by stacking a back electrode, a dielectric layer, a luminescent layer, a dielectric layer, and a transparent electrode in that order, is used. An activator containing Pr, Mn, and Au is mixed into a base material comprised of strontium sulfide (SrS) and the resulting mixture is heated to activate the base material. Then GaAs and InP are added to the mixture, following which the mixture thus prepared is baked in a nitrogen atmosphere containing sulfur gas to produce the luminous body. By mixing the luminous body thus prepared and an ultraviolet curing dielectric substance, the luminescent layer can be obtained.
