Claim 17:
18. A quantum dot, comprising
a core comprising a semiconductor nanocrystal comprising a Group III-V compound; and
a semiconductor nanocrystal shell disposed on the core, the semiconductor nanocrystal shell comprising zinc, selenium, and sulfur,
wherein the quantum dot does not comprise cadmium,
an emission peak wavelength of the quantum dot is in a range of about 500 nanometers to about 550 nanometers,
an ultraviolet-visible absorption spectrum of the quantum dot comprises a first exciton absorption peak having a first peak energy and a second exciton absorption peak having a second peak energy, and
an absolute value of a second derivative of the second peak energy of the second exciton absorption peak is greater than or equal to about 0.001.
