Abstract: Nanoparticles may be formed on a substrate by mixing precursor solutions deposited by an inkjet printer. A first solution is deposited on a substrate from a first inkjet print cartridge. Then, a second solution is deposited on the substrate from a second inkjet print cartridge. The solutions may be printed in an array of droplets on the substrate. Nanoparticles form when droplets of the first solution overlap with droplets of the second solution. In one example, the nanoparticles may be gold nanoparticles formed from mixing a first solution of 1,2-dichlorobenzene (DCB) and oleylamine and a second solution of gold chloride trihydrite and dimethyl sulfoxide (DMSO). The nanoparticles may be incorporated into optoelectronic devices.

Abstract: Patterned multilayer films, such as those used in electronic devices, solar cells, solid oxide fuel cells (SOFCs), and solid oxide electrolysis cells (SOECs) may be deposited and annealed in a single tool. The tool includes an inkjet printer head, a heater, and a laser. The inkjet printer head deposits on a substrate either suspended particles of a functional material or solvated precursors of a functional material. The head is mounted on a support that allows the head to scan the substrate by moving along the support in a first direction and moving the support along a second direction. After the head deposits the material the heater evaporates solvent from substrate, and the depositing and heating may be repeated one or more times to form a patterned multilayer material. Then, a laser, microwave, and/or Joule effect heating device may be used to anneal the multilayer material to a desired pattern and crystalline state.

In fabrication of the component, at least one organic optoelectronically active layer is formed by transferring a liquid-phase organic optoelectronically active material to a layer of the component from a rotating roll having a direct contact with the layer moving along with rotation of the rotating roll.

Abstract: A process for in-situ purification of organic molecules and vapor deposition of the purified molecules involves vaporizing the organic molecules from a crude material, condensing the organic molecules on a glass wool baffle, re-vaporizing the condensed organic molecules, and depositing the re-vaporized organic molecules on a substrate. An apparatus adapted for practicing the process includes a crucible, a glass wool baffle in the crucible above the bottom of the crucible, and a heater configured to heat the crucible and glass wool baffle.

Abstract: Light-emitting chromophores (lumophores) that emit different colored light may be covalently attached to a nanoparticle core such as a silsequioxane. The light emission profile of the resulting lumophore-functionalized nanoparticle is the sum of the light emission of all of the lumophores attached to the nanoparticle. In some embodiments, the lumophore-functionalized nanoparticle is white light-emitting.
