Abstract: This presently disclosed technology relates to Organic Light Emitting Diodes (OLEDs), more particularly it relates to OLED display extraction and nanocomposite formulations that can be used for the light extraction structure. The OLEDs comprise, in order, an encapsulation layer or a substrate layer, an array of lenses, and an array of light emitting pixels at least partially covered by said array of lenses, wherein at least one of the lenses covers at least one of the pixel, and said lenses comprises a material with higher refractive index than the encapsulation layer or substrate layer.

Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

Abstract: An integrated circuit is made by depositing a pinning layer on a substrate. A block copolymer photoresist is formed on the pinning layer. The block copolymer has two blocks A and B that do not self-assemble under at least some annealing conditions. The exposed block copolymer photoresist is processed to cleave at least some block copolymer bonds in the exposed selected regions. The exposed pinning layer is processed to create a chemical epitaxial pattern to direct the local self assembly of the block copolymer.
