A Multifunctional Halide-Equivalent Anion Enabling Efficient CsPb(Br/I)3 Nanocrystals Pure-Red Light-Emitting Diodes with External Quantum Efficiency Exceeding 23%

Jibin Zhang et al.

Summary: In this study, a multifunctional additive of benzenesulfonate (BS-) is introduced into CsPb(Br/I)(3) nanocrystals to improve the efficiency and stability of pure-red perovskite LEDs (PeLEDs). The BS- can passivate defects on the surface of nanocrystals and increase the formation energy of halide vacancies. The electron-withdrawing property of sulfonate group can reduce the self-doping effect and alter the behavior of CsPb(Br/I)(3) nanocrystals. With this strategy, the pure-red PeLEDs achieve a synergistic boost in device performance with CIE coordinates of (0.70, 0.30) and a champion external quantum efficiency of 23.5%, approaching the Rec. 2020 red primary color.

Through selective deposition and elastomer transferring processes, TE devices with excellent mechanical properties were successfully obtained. The fabricated electrodes exhibited uniform electroluminescence under both flat and bending states, indicating their promising potential for flexible optoelectronic applications.

High efficiency green InP quantum dot light-emitting diodes by balancing electron and hole mobility

Wei-Chih Chao et al.

Summary: The development of green-emitting InP quantum dot light-emitting diodes (QLED) is lagging behind their red and green counterparts. By preparing green InP quantum dots and incorporating them into a QLED to promote hole transport and reduce electron mobility, a maximum quantum efficiency of 16.3% is achieved.

Water-passivated ZnMgO nanoparticles for blue quantum dot light-emitting diodes

Yue Guo et al.

Summary: Water is used as a passivation agent to fix the interface between quantum dots (QDs) and magnesium doped zinc oxide (ZnMgO) nanoparticles, which reduces exciton quenching and balances charge carriers to improve the performance of blue quantum dot light-emitting diodes (QLEDs). The passivated ZnMgO leads to significantly higher external quantum efficiency (EQE) and luminance in blue QLEDs compared to those made with pristine ZnMgO. Characterization techniques such as photoluminescence spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy were used to analyze the water-passivated ZnMgO nanoparticles for further understanding of the enhanced performance in blue QLEDs.
