Brighter And Lighter

Full-colour quantum dot displays fabricated by transfer printing

An innovation in LED lighting achieved through the use of quantum dots has greatly increased the¬†efficiency, brightness, lifetime and low turn-on voltage of this¬†energy source. A research team at Seoul National University, South Korea has published their research in a recent issue of Nano Letters. They found that the key to improving the brightness and efficiency of the QLEDs (Quantum Light Emitting Diode) comes from improving the injection of current-carrying electrons and holes into the quantum dots. The more efficiently the electrodes can inject electrons and holes into the quantum dots, the more efficiently QLED can emit light. The anodes… read more
