Method of manufacturing gallium nitride quantum dots

Abstract:

Provided is a method of manufacturing gallium nitride quantum dots. The method includes the steps of: preparing a gallium precursor solution by heating a mixture prepared by dissolving a gallium halide and an organic ligand in a solvent; heating the gallium precursor solution to obtain a heated gallium precursor solution; hot-injecting a nitrogen precursor into the heated gallium precursor solution at a heating temperature to produce gallium nitride; growing the gallium nitride while maintaining the heating temperature, thereby producing a growth-completed gallium nitride; and cooling a solution including the growth-completed gallium nitride to produce gallium nitride quantum dots in a colloid state.
