TL;DR: Perovskite quantum wells yield highly efficient LEDs spanning the visible and near-infrared as discussed by the authors. But their performance is not as good as those of traditional LEDs, and their lifetime is shorter.

TL;DR: It is concluded that the efficiency roll-off in perovskite LEDs is mainly due to luminescence quenching which is likely caused by non-radiative Auger recombination.

TL;DR: The MQW perovskites is a promising platform for achieving high performance visible-range electroluminescence emission through high-throughput processing methods, which is attractive for low-cost lighting and display applications.

TL;DR: High-performance red perovskite light-emitting diodes (PeLEDs) with a luminance of 732 cd m-2 and a maximum external quantum efficiency of 7.3%, which are among the best-performing red PeLEDs are obtained.

TL;DR: It is shown that high-efficiency perovskite LEDs with a high external quantum efficiency of 20.2% and an ultrahigh radiant exitance up to 114.9 mW cm −2 can be achieved by employing the microcavity effect to enhance light extraction and the enhanced microc Cavity effect and light out-coupling efficiency are confirmed by the study of angle-dependent emission profiles.
