    摘要: Disclosed is a deep red phosphor (600 nm to 670 nm) of Mn activity having a chemical formula of (k-x)MgOxAF2GeO2:yMn4+ where k is a real number between 2.8 and 5.0, x is a real number between 0.1 and 0.7, y is a real number between 0.005 and 0.015, and A is Ca, Sr, Ba, Zn, or a mixture thereof, or a mixture of Mg and at least one of Ca, Sr, Ba and Zn. The deep red phosphor has a high excitation efficiency and thus can be applied to light emitting diode (LED) packages, which uses an ultraviolet (UV) light source or a blue light source as an excitation light source. The deep red phosphor is applied to a phosphor layer of a phosphor lamp such as a cold cathode fluorescence lamp (CCFL) and a flat fluorescent lamp (FFL).

    摘要: A multilayered white light emitting diode and a method of fabricating the same include forming a phosphor mixture layer including a green phosphor and a blue phosphor on a UV light emitting diode and forming a red quantum dot layer on the phosphor mixture layer. In the white light emitting diode of the present invention, the quantum dots are excited by green and blue visible light, thus increasing luminescence efficiency and realizing stable white light. Moreover, the white light emitting diode can be widely used as a light source having high output and high efficiency, thus being capable of substituting for a backlight unit of an illumination device or display device.
