  • Patent number: 8941293
    Abstract: Solid state lighting devices containing quantum dots dispersed in polymeric or silicone acrylates and deposited over a light source. Solid state lighting devices with different populations of quantum dots either dispersed in matrix materials or not are also provided. Also provided are solid state lighting devices with non-absorbing light scattering dielectric particles dispersed in a matrix material containing quantum dots and deposited over a light source. Methods of manufacturing solid state lighting devices containing quantum dots are also provided.
    Type: Grant
    Filed: January 28, 2011
    Date of Patent: January 27, 2015
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Kwang-Ohk Cheon, Jennifer Gillies, David Socha, David Duncan, Michael Locasio
  • Patent number: 8409475
    Abstract: A semiconductor nanocrystal composite comprising a semiconductor nanocrystal composition dispersed in an inorganic matrix material and a method of making same are provided. The method includes providing a semiconductor nanocrystal composition having a semiconductor nanocrystal core, providing a surfactant formed on the outer surface of the composition, and replacing the surfactant with an inorganic matrix material. The semiconductor nanocrystal composite emits light having wavelengths between about 1 and about 10 microns.

  • Patent number: 7723744
    Abstract: Light-emitting devices are provided that incorporate one or more underlying LED chips or other light sources and a layer having one or more populations of nanoparticles disposed over the light source. The nanoparticles may absorb some light emitted by the underlying source, and re-emit light at a different level. By varying the type and relative concentration of nanoparticles, different emission spectra may be achieved. White light and specialty-color emission may be achieved. Devices also may include multiple LED chips, with nanoparticles disposed over one or more underlying chips in an array.
