    Abstract: A process of synthesizing Ga—Se nanocrystals is provided, the process including: contacting a first precursor containing gallium with a second precursor containing selenium to obtain a Ga—Se single precursor; and reacting the Ga—Se single precursor in a solvent in the presence of a ligand compound, and optionally with a third precursor including an element (A) other than gallium and selenium, to prepare a Ga—Se nanocrystal represented by Chemical Formula 1: GaSexAy  [Chemical Formula 1] wherein x is about 1.1 to 3, and y is about 0.1 to 4.
