Abstract
A quantum dot including a core including a first semiconductor nanocrystal including zinc, tellurium, and selenium and a semiconductor nanocrystal shell disposed on the core and including zinc, tellurium, selenium, and sulfur, a production method thereof, and an electronic device including the same. The quantum dot is free of cadmium, the quantum dot has a mole ratio of tellurium with respect to selenium of less than or equal to about 0.06:1, a photoluminescence peak wavelength of the quantum dot is greater than or equal to about 450 nm and less than or equal to about 470 nanometers (nm), and a full width at half maximum (FWHM) of a photoluminescence peak of the quantum dot is less than or equal to about 41 nm.
