1. A Group III-V-based quantum dot comprising:
a seed which includes a Group III element, a Group V element, and an active metal having various oxidation numbers and in which a molar ratio of the Group III element and the active metal is 1:3 to 1:30, wherein the active metal is derived from a material represented by [Chemical Formula 1] of TxOy(carboxylate)z when the seed is formed, wherein T is Zn, x, y, and z are natural numbers excluding zero, and x is greater than y, and wherein a shell is included on an outer surface of the seed, and the shell includes a Group VI element and a molar ratio of the Group VI element of the shell and a Group III element of the seed is 1:3 to 1:20.
