METHOD FOR FABRICATING THE CDSE QUANTUM DOT DOPED WITH MG

摘要

A manufacturing method of a cadmium selenide quantum dot doped with magnesium is provided to control the energy band-gap of the cadmium selenide and improve luminous efficiency. A manufacturing method of a cadmium selenide quantum dot doped with magnesium comprises: a step(S110) forming a first solution by dissolving cadmium source and magnesium source in solvent paraffinic oil and oleic acid and forming a second solution by dissolving a selenium(Se) metal in the solvent paraffinic oil; a step(S120) creating the cadmium selenide quantum dot doped with magnesium by adding the first solution in the second solution or the second solution in the first solution; a step(S130) growing the cadmium selenide quantum dot doped with magnesium in order to have predetermined light emission region wavelength and band-gap; and a step(S140) washing the grown cadmium selenide quantum dot doped with magnesium.
