  • Patent number: 8388863
    Abstract: The present invention relates to a phosphor for UV and long-wavelength excitation and a preparation method thereof, more particularly to a phosphor for UV and long-wavelength excitation prepared from a phosphor precursor comprising strontium, barium, zinc, silica and rare-earth metal, wherein the proportion of barium and zinc is optimized to obtain a color coordinate in the range of x=0.50-0.64 and y=0.38-0.51, and a method for preparing the same by heat-treating the phosphor precursor under a mixed gas atmosphere of nitrogen and hydrogen with specific proportion. Since heat treatment is possible even at low temperature, a phosphor for UV and long-wavelength excitation having superior luminescence characteristics and thus offering superior efficiency when applied to diodes or liquid crystal displays can be obtained without having to use conventional flux materials to lower baking temperature and without using toxic substances.

  • Publication number: 20080185602
    Abstract: The present invention relates to a method for preparing a white light emitting diode (LED) using phosphors, especially to a white light emitting diode prepared by applying a tri-color phosphor material mixture of red, blue and green on a UV LED chip made of a packaging substrate, where white light is obtained by transmitting light through the tri-color phosphor mixture since the UV LED chip emits purple light. In particular, the present invention relates to a white light emitting diode prepared by laminating green and red or yellow and red phosphor materials on a blue LED chip, where white light is obtained as light is transmitted and absorbed by the phosphors. The method in accordance with the present invention is advantageous in that a white light emitting diode having superior photoluminescence efficiency can be provided using a single chip.
