<ul><li>A research team from the University of Science and Technology of China has developed the world's brightest pure-red perovskite light-emitting diodes (PeLEDs).</li><li>These new LEDs achieved a peak external quantum efficiency of 24.2% and a maximum brightness of 24,600 cd m-2, setting a new record for pure-red PeLEDs.</li><li>The breakthrough was made possible by addressing carrier leakage issues with a new material design called 3D intragrain heterostructure, which traps electrical charges within light-emitting regions.</li><li>The redesigned PeLEDs demonstrated high efficiency even at extremely bright levels and showed remarkable stability, paving the way for improved displays and lighting technologies.</li></ul>
