Abstract: A method for preparing a sulfide phosphor where a raw material mixture for a sulfide phosphor is placed in an almost closed first heat-resistant container and fired therein, the method being characterized in that an auxiliary material composed of carbon and/or a carbon-forming compound capable of being pyrolyzed at a temperature not higher than the firing temperature to form carbon, and a metal sulfide capable of reacting with the carbon and/or said carbon-forming compound at a temperature not lower than 600°C but not higher than the firing temperature to form a carbon sulfide is placed in the portion as physically separated from the raw material mixture for the sulfide phosphor in the said first heat-resistant container and the firing is conducted under such condition so that said first heat-resistant container may have a carbon sulfide atmosphere by the thermal reaction of the thus fired auxiliary materials.

Abstract: An organic-inorganic hybrid material chelating a metal atom of a metal oxide matrix 103 in a pendant shape is synthesized, where the organic compound (the functional chelating agent) 104 is able to develop a function of a coloring property, a light-emitting property, or semiconductivity by chelating a metal atom. As a synthesis method, sol (a composition for coating application) including a metal alkoxide and/or a metal salt and a functional chelating agent may be prepared and the organic-inorganic hybrid material may be synthesized by sol-gel method.
Due to the above-inentioned structure, it is possible to synthesize an organic-inorganic hybrid material that has an organic group directly bonded to a metal oxide matrix and is able to develop a different function from that of a mere metal oxide.
In other words, it is possible to realize a functional organic-inorganic hybrid material that develops a coloring property, a light-emitting property, or semiconductivity due to the organic group directly bonded to the metal oxide matrix.
