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

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.

Disclosed herein are display systems comprising light-emitting, diodes (LEDs), suitably blue light LEDs, which demonstrate increased optical power output. In embodiments, the display systems include compositions comprising phosphors, including luminescent nanocrystals.

Light emitting diode (LED) devices

Disclosed herein are systems and methods for heating alane etherate compositions for producing microcrystalline alpha alane. An exemplary heating method comprises introducing a preheated solvent into the alane etherate composition and rapidly stirring to effectuate rapid heating of the composition without the need to heat the reactor walls. In this way, the alane etherate composition can be heated while also reducing the risk of decomposition. In further embodiments, a two-stage reactor can be employed for producing alpha alane, wherein the heating occurs in the second stage.
