QLED screens have been on the market for a few years now. They are known for their bright, intense colours, which are produced using what is known as quantum dot technology: QLED stands for quantum dot light emitting diode. Researchers at ETH Zurich have now developed a technology that increases the energy efficiency of QLEDs. By minimising the scattering losses of light inside the diodes, a larger proportion of the light generated is emitted to the outside.

CEA-Leti and Partners Demonstrate Potentially Scalable Readout System for Large Arrays of Quantum Dots
Leti, a technology research institute of CEA Tech, and its research partners have demonstrated a potentially scalable readout technique that could be fast enough for high-fidelity measurements in large arrays of quantum dots. In a paper presented at IEDM 2019, the international research team reported its work on developing a toolkit on a SOI MOSFET-based prototyping platform that enables fast reading of the states of charge and spin. The study explored two gate-based reflectometry readout systems for probing charge and spin states in linear arrangements of MOS split-gate-defined arrays of quantum dots.
Towards High Quality ZnO Quantum Dots Prospective for Biomedical Applications
Recently, scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) and Warsaw University of Technology (WUT) in cooperation with the Interdisciplinary Research Institute of Grenoble (IRIG) used dynamic nuclear polarization (DNP)-enhanced solid state nuclear magnetic resonance (NMR) spectroscopy for detailed characterization of the organic-inorganic interfaces of ZnO QDs prepared by the traditional sol-gel process and the recently developed one-pot self-supporting organometallic (OSSOM) procedure.
