  • Patent number: 9423083
    Abstract: A lighting apparatus includes a housing structure, a light source supported within the housing structure, and a light coversion layer disposed above the light source. The light conversion layer comprises a plurality of non- or low-self absorbing quantum dots (QDs) embedded in a matrix material, each QD having a different light emission profile that is a function of a size and/or composition of the QD, each of the plurality of QDs selected to achieve a defined spectral emission profile for the lighting device when the plurality of QDs is illuminated by the light source.

  • Patent number: 9249354
    Abstract: Networks of semiconductor structures with fused insulator coatings and methods of fabricating networks of semiconductor structures with fused insulator coatings are described. In an example, a method of fabricating a semiconductor structure involves forming a mixture including a plurality of discrete semiconductor nanocrystals. Each of the plurality of discrete semiconductor nanocrystals is discretely coated by an insulator shell. The method also involves adding a base to the mixture to fuse the insulator shells of each of the plurality of discrete nanocrystals, providing an insulator network. Each of the plurality of discrete semiconductor nanocrystals is spaced apart from one another by the insulator network. The base one such as, but not limited to, LiOH, RbOH, CsOH, MgOH, Ca(OH)2, Sr(OH)2, Ba(OH)2, (Me)4NOH, (Et)4NOH, or (Bu)4NOH.

  • Publication number: 20140252274
    Abstract: Quantum dot delivery methods are described. In a first example, a method of delivering or storing a plurality of nano-particles involves providing a plurality of nano-particles. The method also involves forming a dispersion of the plurality of nano-particles in a medium for delivery or storage, wherein the medium is free of organic solvent. In a second example, a method of delivering or storing a plurality of nano-particles involves providing a plurality of nano-particles in an organic solvent. The method also involves drying the plurality of nano-particles for delivery or storage, the drying removing entirely all of the organic solvent.
