  • 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.
