Abstract
Light-Emitting Diodes In article number 2300449, Xueping Song and co-workers synthesize red-, green-, and blue-emitting CQDs using a new reagent engineering strategy, and the aggregation-caused quenching phenomenon of CQDs is effectively suppressed by utilizing the hydrogen bonding network of CQDs and nanocellulose. Fast thin-film encapsulation (approx. 3 min) of high heat dissipation, high-performance multicolor LEDs were achieved based on UV-cured acrylic resin, and high-performance white LEDs were obtained.
