Cover Story: Quantum dots (QDs) are promising nanomaterials for photoluminescence in combination with LEDs, liquid crystal displays, and solar concentrators. However, the optical efficiency of these devices is subjected to the competition between waveguiding and outcoupling. Here, Yera Ussembayev et al. report how tuning the thickness of the QD layer allows controlling the direction of the emitted light. Photoluminescence is entirely outcoupled for monolayers and very thin films, while thicker QD layers waveguide most of the emission toward the edges of the structure. These results offer a new path to boost the efficiency of different light-generating systems. View this paper
