Journal ArticleDOI
Overcoming the electroluminescence efficiency limitations of perovskite light-emitting diodes.
Himchan Cho,Su Hun Jeong,Min-Ho Park,Young-Hoon Kim,Christoph Wolf,Chang-Lyoul Lee,Jin Hyuck Heo,Aditya Sadhanala,NoSoung Myoung,Seunghyup Yoo,Sang Hyuk Im,Richard H. Friend,Tae-Woo Lee +12 more
TL;DR: Efficient organic-inorganic perovskite light-emitting diodes were made with nanograin crystals that lack metallic lead, which helped to confine excitons and avoid their quenching.
Journal ArticleDOI
Multicolored Organic/Inorganic Hybrid Perovskite Light‐Emitting Diodes
Young-Hoon Kim,Himchan Cho,Jin Hyuck Heo,Tae Sik Kim,NoSoung Myoung,Chang-Lyoul Lee,Sang Hyuk Im,Tae-Woo Lee +7 more
TL;DR: Bright organic/inorganic hybrid perov-skite light-emitting diodes are realized by using CH3 NH3 PbBr3 as an emitting layer and self-organized buffer hole-injection layer (Buf-HIL) to facilitate hole injection.
Journal ArticleDOI

TL;DR: In this paper, a one-dopant alloying strategy was proposed to generate smaller, monodisperse colloidal particles (confining electrons and holes, and boosting radiative recombination) with fewer surface defects.
Journal ArticleDOI
Metal halide perovskite light emitters.
TL;DR: The progress of perovskite emitters in two directions of bulk perovSKite polycrystalline films and perovSkite nanoparticles is reviewed, current challenges are described, and future research directions for researchers are suggested to encourage them to collaborate and to make a synergetic effect in this rapidly emerging multidisciplinary field.
Journal ArticleDOI
Improving the Stability of Metal Halide Perovskite Materials and Light-Emitting Diodes
TL;DR: The origins of the instability in PeLEDs are reviewed and the strategies to improve the stability of MHP materials and Pe LEDs are critically reviewed, such as A-site cation engineering, Ruddlesden-Popper phase, suppression of ion migration with additives and blocking layers, fabrication of uniform bulk polycrystalline MHP layers, and fabrication of stable MHP nanoparticles.
