Classification: CPC G  B  C  H | IPC B  C  G  H

Claim 0:
1. A method of producing a quantum dot, comprising
preparing a zinc precursor not comprising a halogen;
reacting a Lewis base with sulfur to prepare a sulfur precursor;
reacting a Lewis acid metal halide comprising a metal with the Lewis base to obtain an acid base adduct comprising the metal and halogen; and
reacting the zinc precursor and the sulfur precursor in the presence of the acid base adduct and a zinc halide to form a first semiconductor nanocrystal comprising zinc and sulfur and produce the quantum dot,
wherein the quantum dot comprises
a core and
a shell disposed on the core,
wherein one of the core and the shell comprises the 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.
