  • Patent number: 7169326
    Abstract: A fluorescent material of terbium aluminum garnet has a formula (Tb3-x-yCexRey) (Al5-zO12Mez), wherein 0<x?0.8, 0<y?2.0, 0<z?1.0, wherein Re is at least one of gadolinium (Gd), rubidium (Rb), thulium (Tm), praseodymium (Pr), samarium (Sm), europium (Eu), dysprosium (Dy), holmium (Ho), erbium (Er), ytterbium (Yb), lutetium (Lu), strontium (Sr), yttrium (Y), vanadium (V), and chromium (Cr), and wherein Me is silicone that is added or substituted. A blue light-emitting diode may be used as an exciting light source for exciting the fluorescent material to generate an excited light. The excited light and the exciting light are mixed to generate a pure white light. The fluorescent material may be produced by a solid reaction method, a combustion method, or a synchronous precipitation method.

  • Publication number: 20050168127
    Abstract: A white light LED is provided. The white light LED includes an exciting light source and a fluorescent powder, wherein the wavelength of the light emitting from the exciting light source is in a range of about 250 nm to about 490 nmt. The fluorescent powder is disposed around the exciting light source to receive the light emitting from the exciting light source. Furthermore, the material of the fluorescent powder includes (Tb3-x-yCexRey)Al5O12, (Me1-x-yEuxRey)3SiO5, YBO3:Ce3+, YBO3:Tb3+, SrGa2O4:Eu2+, SrAl2O4:Eu2+, (Ba,Sr)MgAl10:Eu2+, Mn2+, Y2O3:Eu3+, Y2O3:Bi3+, (Y,Gd)2O3:Eu3+, (Y,Gd)2O3:Bi3+, Y2O2S:Eu3+, Y2O2S:Bi3+, (Me1-xEux)ReS, 6MgO,As2O5:Mn, Mg3SiO4:Mn, BaMgAl10O17:Eu2+ and (Ca,Sr,Ba)5(PO4)3Cl:Eu2+,Gd3+. The white light LED of the invention provides high luminous efficiency and excellent color rendering index.
