  • Light emitting material
    Patent number: 10053622
    Abstract: A composition can include a first moiety capable of being excited to an excited state, and a second moiety capable of accepting excited state energy from the first moiety. The second moiety is capable of emitting light with a FWHM of 15 nm or less when excited. The second moiety can be a J-aggregate and the first moiety can be a semiconductor nanocrystal.
    Type: Grant
    Filed: July 4, 2013
    Date of Patent: August 21, 2018
    Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Jonathan E. Halpert, Jonathan Tischler, Moungi G. Bawendi, Vladimir Bulovic

  • LED array with photodetector
    Publication number: 20050088380
    Abstract: Embodiments of the present invention provide for an array, and corresponding method of forming an array, that includes a plurality of light emitting devices. The light emitting devices are disposed over a substrate, and a photodetector detects light emitted through the substrate from the light emitting devices. Further, a substantially constant brightness may be maintained in a plurality of light emitting devices disposed over the upper surface of a substrate in an array. Light emitted through the substrate from each of the light emitting devices is measured, and the voltage level applied to each of the light emitting devices is varied to maintain a substantially constant brightness level of light emitted from the light emitting devices.
