  • Optically reliable nanoparticle based nanocomposite HRI encapsulant, photonic waveguiding material and high electric breakdown field strength insulator/encapsulant
    Publication number: 20070221939
    Abstract: An optically reliable high refractive index (HRI) encapsulant for use with Light Emitting Diodes (LED's) and lighting devices based thereon. This material may be used for optically reliable HRI lightguiding core material for polymer-based photonic waveguides for use in photonic-communication and optical-interconnect applications. The encapsulant includes treated nanoparticles coated with an organic functional group that are dispersed in an Epoxy resin or Silicone polymer, exhibiting RI˜1.7 or greater with a low value of optical absorption coefficient ?<0.5 cm?1 at 525 nm. The encapsulant makes use of compositionally modified TiO2 nanoparticles which impart a greater photodegradation resistance to the HRI encapsulant.
