Abstract:
An organic electronic layer is formed using a monomer dissolved in a solvent such as formic acid. The solution is oxidized with the aid of an oxidizing agent, chosen such that there are no ionic byproducts resulting therefrom. Additives such as polyacids, acids, salts and electrolytes may be added to the solution.
Abstract:
The position of the recombination zone can be controlled by controlling the mobility of the charge carriers. In an embodiment of the invention, the mobility of the charge carriers within the emissive polymer layer is controlled by the addition of traps—either electron traps, hole traps, or electron/hole traps. The electron traps reduce electron mobility, the hole traps reduce hole mobility, and the electron/hole traps reduce both electron mobility and hole mobility. The electron mobility and/or the hole mobility can be altered using the traps so that the recombination zone is positioned in the emissive polymer layer sufficiently far from the cathode so that quenching is minimized, and sufficiently far from the HTL/emissive polymer layer interface so that lifetime and/or efficiency is improved.
Abstract:
The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.

Abstract:
A transparent conductor including a conductive layer coated on a substrate is described. More specifically, the conductive layer comprises a network of nanowires that may be embedded in a matrix. The conductive layer is optically clear, patternable and is suitable as a transparent electrode in visual display devices such as touch screens, liquid crystal displays, plasma display panels and the like.

Methods of enhancing contrast ratio of conductive nanostructure-based transparent conductors are described. Contrast ratio is significantly improved by reduction of light scattering and reflectivity of the nanostructures through steps of plating the conductive nanostructures followed by etching or oxidizing the underlying conductive nanostructures.
