Abstract: A method for tuning colors of light emitted from semiconductor quantum-dots of a solution by using an oxidation method is provided to tune accurately the colors of light by etching the semiconductor quantum-dots. A semiconductor quantum-dots dispersion process is performed to disperse second to six group semiconductor quantum-dots in a solvent. A surface active agent removal process is performed to remove a surface active agent from a surface of the semiconductor quantum-dots. A color tuning process is performed to tune colors of the light by etching the second to six group semiconductor quantum-dots. The second to six group semiconductor quantum-dots are etched by using hydrogen peroxide formed by an olefin-oxygen reaction. A removal process is performed to remove byproducts from the surface of the second to six group semiconductor quantum-dots.
