As the electron transport layer in quantum dot light‐emitting diodes (QLEDs), ZnO suffers from excessive electrons that lead to luminescence quenching of the quantum dots (QDs) and charge‐imbalance in QLEDs. Therefore, the interplay between ZnO and QDs requires an in‐depth understanding. In this study, DFT and COSMOSL simulations are employed to investigate the effect of sulfur atoms on ZnO. Based...
Quantum Dot Light‐Emitting Diodes
In article number 2307298, Xiao Wei Sun and co‐workers improved quantum dot light‐emitting diodes (QLEDs) by thiol ligands of ZnO. ZnO nanocrystals were modified to reduce electron excess without hindering charge injection. This modification strategy significantly enhanced QLED performance, achieving an external quantum efficiency of over 23% and a long lifetime of...
As an effective ingredient of disinfectants, ClO− inevitably remains in water, which induces potential health hazards such as lung damage and kidney disease. In this study, we synthesized stimulus‐responsive dual‐ligand luminol‐Tb‐GMP coordination polymer nanoparticles (luminol‐Tb‐GMP CPNPs) as highly selective fluorescent probes for the real‐time and visual detection of ClO−. CPNPs consist of Tb3+...
