  • Red emitting phosphor materials for use in LED and LCD applications
    Publication number: 20060169986
    Abstract: Phosphor compositions including those having the formulas A2-xEuxW1-yMoyO6, where A is selected from Y, Gd, Lu, La, and combinations thereof; and where 0.5?x?1.0, 0.01?y?1.0; MmOnX, wherein M is selected from the group of Sc, Y, a lanthanide, an alkali earth metal and mixtures thereof; X is a halogen; 1?m?3; and 1?n?4, and wherein the lanthanide doping level can range from 0.1 to 40% spectral weight; and Eu3+ activated phosphate or borate phosphors. Also disclosed are light emitting devices including a light source and at least one of the above phosphor compositions.

  • Layered phosphor coatings for LED devices
    Patent number: 6917057
    Abstract: A light emitting device comprised of a light emitting diode on a mounting surface, the light emitting diode includes a substrate layer and at least one active region. A resilient substantially transparent and substantially phosphor free polymer layer extends from the mounting surface to above at least one quarter of a height of the substrate layer but below a top surface of the light emitting diode. A second phosphor containing layer extends from the phosphor free polymer layer to above the top surface of the light emitting diode.

  • Electroluminescent laminate with patterned phosphor structure and thick film dielectric with improved dielectric properties
    Patent number: 6771019
    Abstract: A patterned phosphor structure and EL laminate containing same, forming red, green and blue sub-pixel phosphor elements for an AC electroluminescent display. The patterned phosphor structure includes at least a first and a second phosphor emitting light in different ranges of the visible spectrum, but with combined emission spectra contains red, green and blue light, the first and second phosphors being in a layer, arranged in adjacent, repeating relationship to each other to provide a plurality of repeating first and second phosphor deposits.
