  • Solid-state radioluminescent zeolite-containing composition and light sources
    Patent number: 5100587
    Abstract: A new type of RL light source consisting of a zeolite crystalline material, the intralattice spaces of which a tritiated compound and a luminophore are sorbed, and which material is optionally further dispersed in a refractive index-matched polymer matrix.
    Type: Grant
    Filed: December 27, 1990
    Date of Patent: March 31, 1992
    Assignee: The United States of America as represented by the Department of Energy

  • Solid-state radioluminescent compositions
    Patent number: 4997597
    Abstract: A solid state radioluminescent composition for light source comprises an optically clear polymer organic matrix containing tritiated organic materials and dyes capable of "red" shifting primary scintillation emissions from the polymer matrix. The tritiated organic materials are made by reducing, with tritium, an unsaturated organic compound that prior to reduction contains olefinic or alkynylic bonds.
