Balancing Charge Extends Quantum Dot Efficiencies
Technology – Chinese researchers have taken quantum dot (QD) LEDs above 20% external quantum efficiency (EQE) – thought to be the technology’s theoretical maximum – for the first time. By adding an insulator layer to the design structure, a team at Zhejiang University achieved an EQE of 20.5%, with an operational lifetime of 100,000 hours. Previous … Read more
