Journal ArticleDOI
Low trap-state density and long carrier diffusion in organolead trihalide perovskite single crystals
Dong Shi,Valerio Adinolfi,Riccardo Comin,Mingjian Yuan,Erkki Alarousu,Andrei Buin,Yin Chen,Sjoerd Hoogland,Alexander Rothenberger,Khabiboulakh Katsiev,Yaroslav Losovyj,Xin Zhang,Peter A. Dowben,Omar F. Mohammed,Edward H. Sargent,Osman M. Bakr +15 more
TL;DR: An antisolvent vapor-assisted crystallization approach is reported that enables us to create sizable crack-free MAPbX3 single crystals with volumes exceeding 100 cubic millimeters, which enabled a detailed characterization of their optical and charge transport characteristics.
Journal ArticleDOI
High-quality bulk hybrid perovskite single crystals within minutes by inverse temperature crystallization
Makhsud I. Saidaminov,Ahmed L. Abdelhady,Ahmed L. Abdelhady,Banavoth Murali,Erkki Alarousu,Victor M. Burlakov,Wei-Wei Peng,Ibrahim Dursun,Lingfei Wang,Yao-xin He,Giacomo Maculan,Alain Goriely,Tao Wu,Omar F. Mohammed,Osman M. Bakr +14 more
TL;DR: A rapid crystal growth process to obtain MAPbX3 single crystals, an order of magnitude faster than previous reports, and the grown crystals exhibit transport properties and trap densities comparable to the highest quality MAPb X3 reported to date.
Journal ArticleDOI

TL;DR: All-inorganic perovskite nanocrystals containing caesium and lead provide low-cost, flexible and solution-processable scintillators that are highly sensitive to X-ray irradiation and emit radioluminescence that is colour-tunable across the visible spectrum.
Journal ArticleDOI
Highly Efficient Perovskite-Quantum-Dot Light-Emitting Diodes by Surface Engineering
Jun Pan,Li Na Quan,Li Na Quan,Yongbiao Zhao,Wei Peng,Banavoth Murali,Smritakshi P. Sarmah,Mingjian Yuan,Lutfan Sinatra,Noktan M.

TL;DR: A two-step ligand-exchange strategy is developed, in which the long-carbon- chain ligands on all-inorganic perovskite quantum dots (QDs) are replaced with halide-ion-pair ligands.
Journal ArticleDOI
