Abstract

A quantum dot including a semiconductor nanocrystal core and a semiconductor nanocrystal shell disposed on the core and does not include cadmium, wherein the core includes a Group III-V compound, the quantum dot has a maximum photoluminescence peak in a green light wavelength region, a full width at half maximum (FWHM) of the maximum photoluminescence peak is less than about 50 nanometers (nm), and a difference between a wavelength of the maximum photoluminescence peak and a first absorption peak wavelength of the quantum dot is less than or equal to about 25 nanometers, and a production method thereof.
