摘要： Embodiments provide a quantum dot, an optical member including the quantum dot, an electronic apparatus including the quantum dot, and a method of preparing the quantum dot. The quantum dot includes a core including indium (In) and A1, and a first shell covering the core, not including In, and including A1. A1 is a Group I element, an atomic ratio of A1 to In in the quantum dot is in a range of about 0.9 to about 2.4, and the quantum dot emits visible light other than blue light.
