Title: Light-emitting nanocomposite particles

Abstract

A method of making an inorganic light emitting layer includes combining a solvent for semiconductor nanoparticle growth, a solution of core/shell quantum dots, and semiconductor nanoparticle precursor(s); growing semiconductor nanoparticles to form a crude solution of core/shell quantum dots, semiconductor nanoparticles, and semiconductor nanoparticles that are connected to the core/shell quantum dots; forming a single colloidal dispersion of core/shell quantum dots, semiconductor nanoparticles, and semiconductor nanoparticles that are connected to the core/shell quantum dots; depositing the colloidal dispersion to form a film; and annealing the film to form the inorganic light emitting layer.

Light emitting diode with high aspect ratio submicron roughness for light extraction and methods of forming

Patent Li, Ting

The surface morphology of an LED light emitting surface is changed by applying a reactive ion etch (RIE) process to the light emitting surface. High aspect ratio, submicron roughness is formed on the light emitting surface by transferring a thin film metal hard-mask having submicron patterns to the surface prior to applying a reactive ion etch process. The submicron patterns in the metal hard-mask can be formed using a low cost, commercially available nano-patterned template which is transferred to the surface with the mask. After subsequently binding the mask to the surface, the template is removed and the RIE processmore » « less

A conventional semiconductor LED is modified to include a microlens layer over its light-emitting surface. The LED may have an active layer including at least one quantum well layer of InGaN and GaN. The microlens layer includes a plurality of concave microstructures that cause light rays emanating from the LED to diffuse outwardly, leading to an increase in the light extraction efficiency of the LED. The concave microstructures may be arranged in a substantially uniform array, such as a close-packed hexagonal array. The microlens layer is preferably constructed of curable material, such as polydimethylsiloxane (PDMS), and is formed by soft-lithographymore » « less
