Scientists Develop OLED with Radicals to Increase Efficiency

Scientists have developed several types of LED including OLEDs, quantum-dot-based LEDs (QLED), perovskite-based LEDs and Micro LEDs for the purpose of enhancing the brightness, contrast and resolution of displays as well as to reduce the production cost and energy use. A new research published on Nature has illustrated a development of OLEDs using free radicals which generate doublet emission with higher efficiency. In the research, scientists from China and the UK have demonstrated radical-based OLEDs that could reach an external quantum efficiency of ...
