Enhanced color conversion of quantum dots - polymer hybrid films in light emitting diodes

Achieving good light management is key for quantum dots (QDs) - polymer hybrid films, which are increasingly used in display and lighting applications in tandem with light emitting diodes. To overcome the insufficient absorption of blue light by the QDs and light trapping of downshifted emission, we propose an approach based on microcellular foaming in order to engineer porous hybrid films with improved green and red emission.
