Abstract: Disclosed is a light emitting diode using zinc oxide-aminopyrene core-shell quantum dots capable of improving the purity of blue light emission and securing long lifetime through the characteristic that emission transition of electrons proceeds in aminopyrene by applying the zinc oxide-aminopyrene quantum dots forming a core-shell structure with zinc oxide(ZnO) and 1-aminopyrene to the light emitting diode. The light emitting diode using the zinc oxide-aminopyrene core-shell quantum dots comprises a bule light-emitting layer of the ZnO@1-aminopyrene quantum dots having a core-shell structure in which ZnO quantum dots form a core, and 1-aminopyrene forms a shell.
