Powdered quantum dots that can be dispersed into a silicone layer are provided. The powdered quantum dots are a plurality of quantum dot particles, preferably on the micron or nanometer scale. The powdered quantum dots can include quantum dot-dielectric particle complexes or quantum dot-crosslinked silane complexes. The powdered quantum dots can included quantum dot particles coated with a dielectric layer.

Quantum dot particles on the micron or nanometer scale and method of making the same

One embodiment of the invention provides a nanostructure layer, comprising: a first population of semiconductor nanocrystals forming electron transport conduits; a second population of semiconductor nanocrystals forming hole transport conduits; and a third population of semiconductor nanocrystals capable of at least one of the following: absorbing light or emitting light.

Nanostructured layers, methods of making nanostructured layers, and application thereof

A display device that includes an underlying excitation source, a converting layer, and an optical filter layer. The underlying excitation source emits light in a spatial pattern that may or may not be altered in time and has a short wavelength capable of being at least partially absorbed by the overlying converting layer. The converting layer can be a contiguous film or pixels of quantum dots that can be dispersed in a matrix material. This converting layer is capable of absorbing at least a portion of the wavelength(s) of the light from the underlying excitation source and emitting light at one or more different wavelengths. The optical filter layer prevents the residual light from the excitation source that was not absorbed by the converting layer from being emitted by the display device.

A laser gain medium. The novel laser gain medium includes a host material, a plurality of quantum dots dispersed throughout the host material, and a plurality of laser active ions surrounding each of the quantum dots. The laser active ions are disposed in close proximity to the quantum dots such that energy absorbed by the quantum dots is non-radiatively transferred to the ions via a Forster resonant energy transfer, thereby exciting the ions to produce laser output. In an illustrative embodiment, each quantum dot is surrounded by an external shell doped with the laser active ions.

A first population of semiconductor nanocrystals to create electron transport conduits, a second population so semiconductor nanocrystals to create hole transport conduits; and a third population of semiconductor nanocrystals to be used for either light absorption or light emission can be combined to form an inorganic nanostructure layer.

Nanostructured layers, method of making nanostructured layers, and application thereof

A water-stable semiconductor nanocrystal complex and methods of making the same are provided. The water-stable semiconductor nanocrystal complex includes a semiconductor nanocrystal composition, a surfactant layer, and an outer layer. The outer layer and/or the surfactant layer can be cross-linked.

Water-stable semiconductor nanocrystal complexes and methods of making same

A high-refractive index material that includes semiconductor nanocrystal compositions. The high-refractive index material has at least one semiconductor nanocrystal composition incorporated in a matrix material and has a refractive index greater than 1.5. The semiconductor nanocrystal composition has a semiconductor nanocrystal core of a II-VI, III-V, or IV-VI semiconductor material. A method of making a high-refractive index material includes incorporating, at least one semiconductor nanocrystal composition in a matrix material. An application of a high-refractive index material includes incorporating at least one semiconductor nanocrystal composition in a matrix material to form the high-refractive index material and depositing the high-refractive index material on the surface of a lighting device.
