  • Patent number: 11881543
    Abstract: Multi-phase polymer films containing quantum dots (QDs) are described herein. The films have domains of primarily hydrophobic polymer and domains of primarily hydrophilic polymer. QDs, being generally more stable within a hydrophobic matrix, are dispersed primarily within the hydrophobic domains of the films. The hydrophilic domains tend to be effective at excluding oxygen.
    Type: Grant

  • Patent number: 10941338
    Abstract: Highly stable films containing semiconductor nanoparticles (“quantum dots”) are prepared from resins containing a fast-curing inner phase having a high glass transition temperature (Tg) and certain inner phase/outer phase combinations. The resins may comprise an inner phase and outer phase (but may appear to be a single phase due to their homogeneous appearance when viewed using an optical microscope). The method provides a highly scalable and cost-effective procedure for preparing films that are resistant to light, elevated temperatures, moisture, and oxygen.

  • Patent number: 9840665
    Abstract: Multi-phase polymer films of quantum dots (QDs) and their use in light emitting devices (LEDs) are disclosed. The QDs are absorbed in a host matrix, which dispersed within an outer polymer phase. The host matrix is hydrophobic and is compatible with the surface of the QDs. The host matrix may also include a scaffolding material that prevents the QDs from agglomerating. The outer polymer is typically more hydrophilic and prevents oxygen from contacting the QDs.

  • Patent number: 9663710
    Abstract: It has been discovered that certain silicon-containing, surface-modifying ligands can be used to make semiconductor nanoparticles (quantum dots) more compatible with polysiloxanes. Quantum dots dispersed in a polysiloxane matrix may be used, for example, in light-emitting devices to alter the emission spectrum of such devices.
