Patent number: 11374172Abstract: Methods and systems for organic vapor jet deposition are provided, where an exhaust is disposed between adjacent nozzles. The exhaust may reduce pressure buildup in the nozzles and between the nozzles and the substrate, leading to improved deposition profiles, resolution, and improved nozzle-to-nozzle uniformity. The exhaust may be in fluid communication with an ambient vacuum, or may be directly connected to a vacuum source.Type: GrantFiled: December 21, 2010Date of Patent: June 28, 2022Assignees: The Regents of the University of Michigan, The Trustees of Princeton UniversityInventors: Stephen Forrest, Richard Lunt

Patent number: 9054335Abstract: A first device is provided. The first device includes an organic light emitting device, which further comprises a first electrode, a second electrode, and an organic emissive layer disposed between the first and second electrode. Preferably, the second electrode is more transparent than the first electrode. The organic emissive layer has a first portion shaped to form an indentation in the direction of the first electrode, and a second portion shaped to form a protrusion in the direction of the second electrode. The first device may include a plurality of organic light emitting devices. The indentation may have a shape that is formed from a partial sphere, a partial cylinder, a pyramid, or a pyramid with a mesa, among others. The protrusions may be formed between adjoining indentations or between an indentation and a surface parallel to the substrate.Type: GrantFiled: December 20, 2013Date of Patent: June 9, 2015Assignee: The Regents of the University of MichiganInventors: Stephen R. Forrest, Michael Slootsky, Richard Lunt

Patent number: 8017863Abstract: A photoactive device includes a photoactive region disposed between and electrically connected to two electrodes where the photoactive region includes a first organic photoactive layer comprising a first donor material and a second organic photoactive layer comprising a first acceptor material. The first donor material contains photoactive polymer-wrapped carbon nanotubes and the photoactive region includes one or more additional organic photoactive material layers disposed between the first donor material layer and the acceptor material layer. The photoactive region creates excitons upon absorption of light in the range of about 400 nm to 1450 nm.Type: GrantFiled: April 7, 2009Date of Patent: September 13, 2011Assignee: The Regents of the University of MichiganInventors: Stephen R.
