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.
Claims18
A light-emitting polymer composition comprising:
- a polysiloxane polymer including tritium that emits radiation;
- and
- a wavelength-shifter chemically bonded to the polysiloxane polymer or chemically bonded to a siloxane carrier dispersed within the polysiloxane polymer, the wavelength-shifter emitting visible light in response to the radiation.
A light source comprising:
- a polysiloxane polymer including tritium that emits radiation;
- and
- a wavelength-shifter chemically bonded to the polysiloxane polymer or chemically bonded to a siloxane carrier dispersed within the polysiloxane polymer, the wavelength-shifter emitting visible light in response to the radiation.
An energy source comprising:
- a light-emitting polymer comprising a polysiloxane polymer having tritium that emits radiation and a wavelength-shifter chemically bonded to the polysiloxane polymer or chemically bonded to a siloxane carrier dispersed within the polysiloxane polymer, the wavelength-shifter emitting visible light in response to the radiation;
- and
- a photoelectric device adjacent to the light-emitting polymer and operable to provide an electric current in response to the light.
