White light emitting diode and its manufacture method

A white light-emitting diode is provided to exhibit light-emitting spectrum of broad wavelength, color rendering index and optical properties and to be useful as light sources of various lighting devices. A white light-emitting diode including a light emitting material comprises a light emitting diode chip(100) emitting the light; and a luminescent material consisting of Ce^(3+)-doped silicate fluorescent substance(120) excited by the light emitting diode chip and CdSe-based quantum dot(130). The light emitting diode chip com comprises a blue light emitting diode or long wavelength UV light emitting diode.
