Abstract:
1. A light-emitting device comprising: a first electrode; a second electrode provided to be opposite to the first electrode; and a light-emitting layer which contains a metal oxide semiconductor porous body, by the surface of which an organic light-emitting material is supported, and is provided between the first electrode and the second electrode, wherein a functional group in the organic light-emitting material is esterified with a hydroxyl group (—OH) existing on the surface of the metal oxide semiconductor porous body to immobilize the organic light-emitting material, such that the organic light-emitting material is chemisorbed to the surface of the metal oxide semiconductor porous body, and wherein the functional group is selected from the group consisting of a carboxyl group (—COOH), a thiocarboxyl group (—CSOH), a dithiocarboxyl group (—CSSH), a sulfo group (—SO
