  • Quantum Dot Light-Emitting Diodes for Phototherapy
    Publication number: 20140277297
    Abstract: Disclosed herein are articles for use in phototherapy utilizing quantum dots (QDs). One embodiment is a medical dressing having an occlusive layer and translucent layer. Quantum dot light-emitting diode chips are configured within the occlusive layer to provide light of a specific wavelength for use in phototherapy. Another embodiment is a medical dressing having an occlusive layer and translucent layer, wherein quantum dot material is embedded or impregnated within one or both layers.

  • Cu2XSnY4 Nanoparticles
    Publication number: 20140264192
    Abstract: Materials and methods for preparing Cu2XSnY4 nanoparticles, wherein X is Zn, Cd, Hg, Ni, Co, Mn or Fe and Y is S or Se, (CXTY) are disclosed herein. The nanoparticles can be used to make layers for use in thin film photovoltaic (PV) cells. The CXTY materials are prepared by a colloidal synthesis in the presence of labile organo-chalcogens. The organo-chalcogens serves as both a chalcogen source for the nanoparticles and as a capping ligand for the nanoparticles.

  • Multi-Layer-Coated Quantum Dot Beads
    Publication number: 20140264196
    Abstract: Disclosed herein are coated beads made of a primary matrix material and containing a population of quantum dot nanoparticles. Each bead has a multi-layer surface coating. The layers can be two or more distinct surface coating materials. The surface coating materials may be inorganic materials and/or polymeric materials. A method of preparing such particles is also described. The coated beads are useful for composite materials for applications such as light-emitting devices.

  • Illuminated Signage Using Quantum Dots
    Publication number: 20140098515
    Abstract: An illuminated sign has a primary light source in spaced apart relation to a transparent or translucent substrate having quantum dot phosphors printed or coated thereon. The primary light source may be a blue LED, a white LED or an LED having a significant portion of its emission in the ultraviolet region of the spectrum. The LED may be a backlight for the transparent or translucent substrate and/or an edge light, a down light or an up light.

  • Group XIII Selenide Nanoparticles
    Publication number: 20140011317
    Abstract: A method of preparing Group XIII selenide nanoparticles comprises reacting a Group XIII ion source with a selenol compound. The nanoparticles have an MxSey semiconductor core (where M is In or Ga) and an organic capping ligand attached to the core via a carbon-selenium bond. The selenol provides a source of selenium for incorporation into the semiconductor core and also provides the organic capping ligand. The nanoparticles are particularly suitable for solution-based methods of preparing semiconductor films.
