Quantum dots (QDs) are encapsulated within microbeads having a silyl surface shell. The microbeads are prepared by copolymerizing unsaturated resins and an unsaturated organosilane in the presence of QDs. During the copolymerization, the unsaturated resin and the organosilane phase separate, forming beads having a silyl surface shell surrounding an essentially unsilylated interior. The QDs are encapsulated within the interior. The silyl shell provides a barrier against oxygen and other contaminants diffusing into the bead and reacting with the QDs.

Preparation of quantum dot beads having a silyl surface shell

A formulation incorporates nanoparticles, particularly quantum dot (QD) nanoparticles, into an optically clear medium (resin) to be used as a phosphor material in lighting and display applications, and as a down converting phosphor material in LEDs (light emitting diodes). The resin is compatible with QDs to allow high performance and stability of QD-based LEDs, lighting and display applications.
