In recent years, the performance of perovskite quantum dots (QDs) and QD‐based light‐emitting diodes (QLEDs) has improved greatly, with electroluminescence (EL) efficiency of green and red emission exceeding 20%. However, the development of perovskite near‐infrared (NIR) QLEDs has reached stagnation, where the reported maximum EL efficiency is still below 6%, limiting their further applications. In...
Perovskite Light‐Emitting Diodes
A comprehensive optimization strategy leads to high‐efficiency near‐infrared quantum dot (QD)‐based light‐emitting diodes (QLEDs), as reported in article 2109785 by Zong‐Liang Tseng, Shun‐Wei Liu, Ken‐Tsung Wong, and co‐workers. Post‐treatment of encapsulated FAPbI3 QDs reduces QD surface defects, and the passivated QDs dispersed in n‐octane are effectively spin‐coated...
