CsPbX 3 /poly(maleic anhydride‐ alt ‐1‐octadecene) (PMAO) quantum dots with good crystallinity and stability are fabricated, as described by Jun Dai and co‐workers in article number 2000498 . These quantum dots present longer photoluminescence lifetime, higher photoluminescence quantum yields, and slower intraband hot‐exciton relaxation. White light‐emitting diode devices are fabricated by integrating the green and red CsPbX 3 /PMAO quantum dots on blue GaN chips, showing stable white‐light emission.
