A light emitting device having a substrate and a luminous layer provided overlying the substrate, which includes a semiconductor nanocrystal to which a carbazole derivative is coordination-bonded or attached, the carbazole derivative having aromatic rings of a compound represented by the chemical structure 1 having one to three substitution groups:
where Ar 1 and Ar 2 independently represent substituted or non-substituted aryl groups that may share a linkage to form a ring with a benzene ring, heterocyclic groups, and hydrogen atoms and Ar 3 represents a substituted or non-substituted aryl group, the one to three substitution groups represented by the chemical structure 2:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -X-Y-Z€ƒ€ƒ€ƒChemical Structure 2
where X represents a methylene group, a carbonyloxy group, an oxycarbonyl group, a carbonyl group, an oxygen atom, and a sulfur atom, Y represents a substituted or non-substituted alkylene group, and Z represents a carboxyl group, a hydroxyl group, and a thiol group. |
