  • Garnet phosphor materials having enhanced spectral characteristics
    Patent number: 7252787
    Abstract: Phosphor compositions having the formula (Y1-x-y-zTbxGdyCez)3(M1M2)t(Al1-r-sGarIns)A-2tO12+D, where M1 is Mg or Zn, M2 is Si or Ge, 0<x+y<1, 0.01<z<0.1, 0.1<t<1.5, 0<r, s<0.5, 4.5<A<5.0, and ?1<D<1. Also disclosed are light emitting devices including a light source and at least one phosphor having the above formula. Such phosphors exhibit a deeper red emission when compared to conventional TAG phosphors, allowing the production of white light sources having improved properties.
    Type: Grant
    Filed: August 4, 2004
    Date of Patent: August 7, 2007
    Assignee: General Electric Company
    Inventors: Dan Hancu, Alok Mani Srivastava, Gopi Chandran, Holly Ann Comanzo, Shankar Venugopal, Anant Achyut Setlur, Linda Briel
