Abstract
A quantum dot, a method of preparing the quantum dot, and an optical member and an electronic device, each including the quantum dot, are provided. The quantum dot includes: a core including a Group III-V semiconductor compound alloyed with gallium (Ga); a first shell surrounding the core; and a second shell surrounding the first shell, wherein the first shell includes a first compound that includes a Group II-VI semiconductor compound, a Group III-V semiconductor compound, or a Group III-VI semiconductor compound, the second shell includes a second compound that includes a Group II-VI semiconductor compound, a Group III-V semiconductor compound, or a Group III-VI semiconductor compound, the first compound and the second compound are different from each other, and the atomic percentages of specific elements in a material of the core, elemental ratios in the first shell and second shell with respect to the core satisfy certain ranges.
