  • METHOD AND SYSTEM FOR MANUFACTURING PHOTO-LUMINESCENT WAVELENGTH CONVERSION COMPONENT
    Publication number: 20130093311
    Abstract: An approach is described for manufacturing wavelength conversion components for lighting devices which employ in-line process controls to minimize the amount of perceptible variation in the amount of photo-luminescent material that is deposited in the wavelength conversion components. Weight measurements are utilized in the manufacturing process to control and minimize the amount of the variations. In this approach, the weight of the product during manufacturing is used as a surrogate to a measure of the amount of photo-luminescent material in the component, and hence a surrogate for the expected color properties of the manufactured product. By measuring and checking for weight variations for the component, one can quickly determine with reasonable confidence whether there are any variations in the amount of photo-luminescent in the component.

  • Nano-YAG:Ce phosphor compositions and their methods of preparation
    Patent number: 8414796
    Abstract: Disclosed herein are cerium doped, garnet phosphors emitting in the yellow region of the spectrum, and having the general formula (Y,A)3(Al,B)5(O,C)12:Ce3+, where A is Tb, Gd, Sm, La, Sr, Ba, Ca, and/or Mg, and substitutes for Y, B is Si, Ge, B, P, and/or Ga, and substitutes for Al, and C is F, Cl, N, and/or S, where C substitutes for O. Relative to a solid-state-reaction method, the instant co-precipitation methods provide a more homogeneous mixing environment to enhance the distribution of the Ce3+ activator in the YAG matrix. Such a uniform distribution has the benefit of an increased emission intensity. The primary particle size of the as-prepared phosphor is about 200 nm, with a narrow distribution.
