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.
