Claim 9:
10. The light-emitting device of claim 9, wherein the organic ligand is a group represented by one of Formulae 1A to 1E, or any combination thereof:

*—(Z1)a1—N(Z11)(Z12)  Formula 1A

*—(Z1)a1—P(Z11)(Z12)  Formula 1B

*—(Z1)a1—S(Z11)Formula 1C

*—(Z1)a1—C(═O)O(Z11)Formula 1D

*—(Z1)a1—P(═O)(Z11)(Z12)  Formula 1E

wherein, in Formulae 1A to 1E,
Z1 is a single bond, *—O—*′, *—S—*′, *—C(═O)—*′, a C1-C60 alkylene group unsubstituted or substituted with at least one R1a, a C2-C60 alkenylene group unsubstituted or substituted with at least one R1a, a C3-C60 carbocyclic group unsubstituted or substituted with at least one R1a, or a C1-C60 heterocyclic group unsubstituted or substituted with at least one R1a,
a1 is an integer in a range from 1 to 10, and when a1 is 2 or more, two or more of Z1(s) are identical to or different from each other,
Z11 and Z12 are each independently hydrogen, deuterium, a C1-C60 alkyl group unsubstituted or substituted with at least one R1a, a C2-C60 alkenyl group unsubstituted or substituted with at least one R1a, a C2-C60 alkynyl group unsubstituted or substituted with at least one R1a, a C1-C60 alkoxy group unsubstituted or substituted with at least one R1a, a C3-C60 carbocyclic group unsubstituted or substituted with at least one R1a, or a C1-C60 heterocyclic group unsubstituted or substituted with at least one R1a,
R1a is hydrogen, deuterium, —F, —CI, —Br, —I, a hydroxyl group, a cyano group, a nitro group, a C1-C60 alkyl group, a C2-C60 alkenyl group, a C2-C60 alkynyl group, a C1-C60 alkoxy group, a C3-C60 carbocyclic group, or a C1-C60 heterocyclic group, and
* indicates a binding site to the surface of the shell.
