A LUMINOUS BODY

摘要

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.
