Quantum dots and methods of making quantum dots are described. A method begins with forming quantum dots having a core-shell structure with a plurality of ligands on the shell structure. The method includes exchanging the plurality of ligands with a plurality of second ligands. The plurality of second ligands have a weaker binding affinity to the shell structure than the plurality of first ligands. The plurality of second ligands are then exchanged with hydrolyzed alkoxysilane to form a monolayer of hydrolyzed alkoxysilane on a surface of the shell structure. The method includes forming a barrier layer around the shell structure by using the hydrolyzed alkoxysilane as a nucleation center.

Quantum dot encapsulation techniques

The present disclosure provides nanostructure compositions and methods of producing nanostructure compositions. The nanostructure compositions comprise at least one population of nanostructures, at least one poly(alkylene oxide) ligand bound to the surface of the nanostructures, and optionally at least one organic resin. The present disclosure also provides nanostructure films comprising a nanostructure layer and methods of making nanostructure films.

Peg-based ligands with enhanced dispersibility and improved performance

Embodiments of a display device are described. A display device includes a backlight unit having a light source and a liquid crystal display (LCD) module. The LCD module includes a phosphor film and a filter element. The phosphor film is configured to receive a primary light, from the light source, having a first peak wavelength and to convert a portion of the primary light to emit a secondary light having a second peak wavelength. The second peak wavelength is different from the first peak wavelength. The filter element is optically coupled to the phosphor film and is configured to allow the secondary light to pass through the filter element and to block an unconverted portion of the primary light from passing through the filter element.

Nanostructure based display devices

Embodiments of a display device including barrier layer coated quantum dots and a method of making the barrier layer coated quantum dots are described. Each of the barrier layer coated quantum dots includes a core-shell structure and a hydrophobic barrier layer disposed on the core-shell structure. The hydrophobic barrier layer is configured to provide a distance between the core-shell structure of one of the quantum dots with the core-shell structures of other quantum dots that are in substantial contact with the one of the quantum dots. The method for making the barrier layer coated quantum dots includes forming reverse micro-micelles using surfactants and incorporating quantum dots into the reverse micro-micelles. The method further includes individually coating the incorporated quantum dots with a barrier layer and isolating the barrier layer coated quantum dots with the surfactants of the reverse micro-micelles disposed on the barrier layer.
