Reducing the impact of Auger recombination in quasi-2D perovskite light-emitting diodes

Yuanzhi Jiang et al.

Summary: By reducing the exciton binding energy of materials and employing a polar molecule for treatment, the Auger recombination effect in perovskite materials has been successfully suppressed, leading to efficient PeLEDs devices with outstanding photoluminescence quantum yields. Additionally, a record luminance of 82,480 cd m(-2) was achieved due to the suppressed efficiency roll-off, making it one of the brightest visible PeLEDs to date.

Perovskite Light-Emitting Diodes with Near Unit Internal Quantum Efficiency at Low Temperatures

Yarong He et al.

Summary: Room-temperature-high-efficiency light-emitting diodes based on metal halide perovskite FAPbI(3) exhibit excellent performance at low temperatures, with increased quantum efficiency and stability. The enhanced EQE at low temperatures is attributed to the increased photoluminescence quantum efficiencies of the perovskite, leading to an increased radiative recombination rate.

Suppression of temperature quenching in perovskite nanocrystals for efficient and thermally stable light-emitting diodes

Mingming Liu et al.

Summary: Fluoride-treated CsPbBr3 nanocrystals exhibit near unity emission efficiency at temperatures up to 373 K, with constant decay kinetics. The treatment leads to surfaces rich in fluorine with wider energy gaps than the core, suppressing carrier trapping and improving thermal stability. Devices incorporating these nanocrystals show low turn-on voltage and high external quantum efficiency, with nearly 80% efficiency maintained at high temperatures, offering a promising pathway for high-performance light-emitting diodes based on perovskite nanostructures.

Summary: The performance of perovskite light-emitting diodes tends to decline as the active area increases, with severe phase-segregation identified as the cause. The introduction of L-Norvaline to construct an intermediate phase has successfully suppressed the phase-segregation, resulting in highly-efficient large-area quasi-2D films.
