Patent number: 8362684Abstract: A light-emitting device comprising a population of quantum dots (QDs) embedded in a host matrix and a primary light source which causes the QDs to emit secondary light and a method of making such a device. The size distribution of the QDs is chosen to allow light of a particular color to be emitted therefrom. The light emitted from the device may be of either a pure (monochromatic) color, or a mixed (polychromatic) color, and may consist solely of light emitted from the QDs themselves, or of a mixture of light emitted from the QDs and light emitted from the primary source. The QDs desirably are composed of an undoped semiconductor such as CdSe, and may optionally be overcoated to increase photoluminescence.Type: GrantFiled: May 7, 2012Date of Patent: January 29, 2013Assignee: Massachusetts Institute of TechnologyInventors: Moungi G. Bawendi, Jason Heine, Klavs F. Jensen, Jeffrey N. Miller, Ronald L. Moon

Patent number: 6713955Abstract: An organic light emitting device having a process compatible current self-limiting (CSL) structure applied in the vicinity of an electrode of the device prevents the occurrence of high current flow in the vicinity of a short within the device. Should a short occur, the CSL structure becomes resistive, or non-conducting in the vicinity of the short, thus preventing the occurrence of “runaway” current in the vicinity of the short. By limiting the current flow between conductors in the device, the non-emissive areas of the device can be minimized, thus improving the overall reliability of the device.Type: GrantFiled: November 20, 1998Date of Patent: March 30, 2004Assignee: Agilent Technologies, Inc.Inventors: Daniel B.
