Abstract
A quantum dot includes: a core including a first semiconductor nanocrystal, and a shell disposed on the core, the shell including a second semiconductor nanocrystal and a dopant, wherein the first semiconductor nanocrystal includes a Group III-V compound, the second semiconductor nanocrystal includes zinc (Zn), sulfur (S), and selenium, and the dopant includes lithium, a Group 2A metal having an effective ionic radius less than an effective ionic radius of Zn2+, a Group 3A element having an effective ionic radius less than an effective ionic radius of Zn2+, or a combination thereof. Also a method of producing the quantum dot, and a composite, and an electronic device including the quantum dot.
