Abstract: Provided are a method of preparing quantum dots, a quantum dot prepared by the method, an optical member including the quantum dot, and an electronic apparatus including the quantum dot. The method includes: preparing a mixture of a semiconductor compound including indium (In), a first precursor including a first metal element, a second precursor including a second metal element, a third precursor including a third element, and a fourth precursor including a fourth element; and heating the mixture, wherein the first precursor and the second precursor are different from each other, and the third precursor and the fourth precursor are different from each other.
