Abstract
In a method of manufacturing a quantum dot, a core may be formed using (utilizing) at least one cation precursor and at least one anion precursor. The core may be reacted with a shell forming precursor and a ligand forming precursor for more than one hour to form a shell enclosing the core and a ligand. A nanoparticle including the core, the shell and the ligand may be washed.
