Abstract: A quantum dot includes a core including InP, a first shell around (e.g., surrounding) the core and including ZnTeSe, a second shell around (e.g., surrounding) the first shell and including ZnSe, and a third shell around (e.g., surrounding) the second shell and including ZnS, wherein the ratio of the number of moles of the Te in the first shell to the number of moles of the P in the core is about 0.02 to about 0.90.
