Patent number: 11881543Abstract: 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: GrantFiled: December 27, 2022Date of Patent: January 23, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Cong-Duan Vo, Imad Naasani, Amilcar Pillay Narrainen

Patent number: 10941338Abstract: 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.Type: GrantFiled: February 15, 2019Date of Patent: March 9, 2021Assignee: Nanoco Technologies Ltd.Inventors: Amilcar Pillay Narrainen, Cong-Duan Vo, Imad Naasani, Abu Mohammad Imroz Ali

Patent number: 9840665Abstract: 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.Type: GrantFiled: June 23, 2017Date of Patent: December 12, 2017Assignee: Nanoco Technologies Ltd.Inventors: Cong-Duan Vo, Imad Naasani, Amilcar Pillay Narrainen, Yien Ta, Emma Cherie Hogarth, Alexandra Shannon, Ross Jalmari Mera-Pirttijarvi, Elliot Stuart Poucher
