  • Light-emitting polymer
    Patent number: 8697982
    Abstract: A radiation-emitting polymer composition includes a polysiloxane polymer including tritium and a wavelength-shifter chemically bonded as a side chain to the polysiloxane polymer or chemically bonded as a side chain to a siloxane carrier dispersed within the polysiloxane polymer. The wavelength-shifter includes a plurality of cyclic chemical moieties and emits electromagnetic radiation in response to radiation emitted by the tritium.
    Type: Grant
    Filed: October 28, 2013
    Date of Patent: April 15, 2014
    Assignee: LEP America, Incorporated
    Inventors: James W. Smith, Bruce McKague

  • Light-emitting polymer
    Patent number: 8569610
    Abstract: A light-emitting polymer composition includes a polysiloxane polymer having tritium that emits radiation and a wavelength-shifter chemically bonded to the polysiloxane polymer or a siloxane carrier dispersed within the polysiloxane polymer. The wavelength-shifter emits light in response to the radiation.
