  • Patent number: 10593901
    Abstract: A process for improving the external quantum efficiency of a light emitting diode (LED) is provided by exposing one or more components of an LED, a partially assembled LED, or a completely assembled LED to an amount of hydrogen or hydrogen gas, or to an atmosphere containing higher quantities of hydrogen or hydrogen gas for a period of exposure time. Kits and processes for constructing a light emitting diode having an improved external quantum efficiency is further provided, which includes exposing one or more components of an LED, a partially assembled LED, or a completely assembled LED to an amount of hydrogen or hydrogen gas, or to an atmosphere containing higher quantities of hydrogen or hydrogen gas for a period of exposure time.

  • Patent number: 9887318
    Abstract: A quantum dot for emitting light under electrical stimulation has a center of a first composition and a surface of a second composition. The second composition is different than the first composition. An intermediate region extends between the center and surface and has a continuous composition gradient between the center and the surface. The quantum dot is synthesized in a one pot method by controlling the rate and extent of a reaction by controlling the following parameters: (i) type and quantity of reactant, (ii) reaction time, and (iii) reaction temperature.

  • Patent number: 9780256
    Abstract: A method for synthesizing a quantum dot light emitting diode by providing a glass substrate. A QD-LED stack is formed upon the glass substrate. This QD-LED stack is diffused with an active reagent. The QD-LED stack is encapsulated with a curable resin. The curable resin is cured with UV light.
