1. A quantum dot comprising
a core and
a shell disposed on the core,
wherein one of the core and the shell comprises a first semiconductor nanocrystal comprising zinc and sulfur and the other of the core and the shell comprises a second semiconductor nanocrystal having a different composition from the first semiconductor nanocrystal,
the first semiconductor nanocrystal further comprises a metal and a halogen configured to act as a Lewis acid in a halide form,
an amount of the metal is greater than or equal to about 10 mole percent, based on a total number of moles of sulfur, and
an amount of the halogen is greater than or equal to about 10 mole percent, based on the total number of moles of sulfur.
