  • Publication number: 20190344505
    Abstract: According to some aspects, a de-powdering subsystem for an additive fabrication system is described. The de-powdering subsystem may comprise a bath subsystem. The bath subsystem may comprise a reservoir configured to contain a liquid and to accept objects to be de-powdered into the liquid, and an agitation facility configured to cause currents within the liquid. The agitator facility may be at least one of (i) a pump configured to circulate the liquid within the reservoir, (ii) a heating element configured to generate convection currents in the liquid, and (iii) a stirrer driven through a linkage to a motor. The bath subsystem may comprise at least one ultrasonic transducer configured to apply ultrasonic vibrations to the liquid within the reservoir.

  • Publication number: 20180122613
    Abstract: Systems and methods are described that relate to quantum dot (QD) structures for lighting applications. In particular, quantum dots and quantum dot containing inks (comprising mixtures of different wavelength quantum dots) are synthesized for desired optical properties and integrated with an LED source to create a trichromatic white light source. The LED source may be integrated with the quantum dots in a variety of ways, including through the use of a small capillary filled with quantum dot containing ink or a quantum dot containing film placed appropriately within the optical system. These systems may result in improved displays characterized by higher color gamuts, lower power consumption, and reduced cost.

  • Publication number: 20170283691
    Abstract: The present invention relates to a composition including quantum dots and an emission stabilizer, products including same, and methods, including methods for improving, or enhancing the emission stability of quantum dots. Inclusion of an emission stabilizer in a composition can improve or enhance the stability of at least one emissive property of the quantum dots in the composition against degradation compared to a composition that is the same in all respects except that it does not include the emission stabilizer. Examples of such emissive properties include, by way of example only, lumen output, lumen stability, color point (e.g., CIE x, CIE y) stability, wavelength stability, FWHM of the major peak emission, absorption, solid state EQE, and quantum dot emission efficiency.
