  • Patent number: 10273407
    Abstract: Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape).

  • Patent number: 9397310
    Abstract: A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, a cathode and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material, that includes nanocrystals. The phosphorescent emissive dopant is bonded to the host material by a bridge moiety.

  • Publication number: 20140203259
    Abstract: A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material. The host material includes inorganic nanocrystals where (i) at least 50% of ligands bonded to said nanocrystals are compact ligands, (ii) an average interparticle distance between adjacent nanoparticles is ?1 nm, or (iii) both. Also described are a method of making the emissive layer and a composition that includes the phosphorescent emissive dopant with the host materials that include the electronically-coupled inorganic nanocrystal host material.
