Abstract

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.
