1. A quantum dot comprising:
a core comprising a Group III-V semiconductor compound alloyed with gallium (Ga);
a first shell around the core; and
a second shell around the first shell,
wherein the first shell comprises a first compound, which comprises a Group II-VI semiconductor compound, a Group III-V semiconductor compound, or a Group III-VI semiconductor compound,
the second shell comprises a second compound, which comprises a Group II-VI semiconductor compound, a Group III-V semiconductor compound, or a Group III-VI semiconductor compound, and the first compound and the second compound are different from each other,
an atomic percentage of gallium in the core to the Group III element excluding Ga in the core is 25 atomic % to 30 atomic %,
an atomic percentage of the Group V or VI element in the first shell to the Group III element in the core is 5 atomic % to 50 atomic %, and
an atomic percentage of the Group V or VI element in the second shell to the Group III element in the core is 5 atomic % to 50 atomic %.
