摘要： A method of preparing a quantum dot, a quantum dot prepared by the method, and an optical member and an electronic apparatus that include the quantum dot are provided. The method includes injecting a first solvent into a first reaction vessel, preparing a first composition by injecting a first semiconductor compound into the first reaction vessel, and forming a first shell by injecting a second composition including the second precursor into the first reaction vessel.
