Journal ArticleDOI
Shape and phase evolution from CsPbBr3 perovskite nanocubes to tetragonal CsPb2Br5 nanosheets with an indirect bandgap
TL;DR: The experimental results and DFT simulation results indicated that the tetragonal CsPb2Br5 is an indirect bandgap semiconductor that is PL-inactive with a bandgap of 2.979 eV.
Journal ArticleDOI
Interface engineering using a perovskite derivative phase for efficient and stable CsPbBr3 solar cells
TL;DR: In this paper, the authors demonstrated CsPbBr3 inorganic perovskite solar cells (PSCs) composed of a derivative-phase C sPb2Br5 for the first time by precisely controlling the film thickness of precursor materials.
Journal ArticleDOI
Enabling Tailorable Optical Properties and Markedly Enhanced Stability of Perovskite Quantum Dots by Permanently Ligating with Polymer Hairs.
Young Jun Yoon,Yajing Chang,Shuguang Zhang,Meng Zhang,Shuang Pan,Yanjie He,Chun Hao Lin,Shengtao Yu,Yihuang Chen,Zewei Wang,Yong Ding,Jaehan Jung,Naresh N. Thadhani,Vladimir V. Tsukruk,Zhitao Kang,Zhiqun Lin +15 more
TL;DR: The selective partition of precursors within the compartment occupied by inner hydrophilic blocks of star-like diblock copolymers imparts in situ formation of robust hairy perovskite QDs permanently ligated by outer hydrophobic blocks via coprecipitation in nonpolar solvent.
Journal ArticleDOI
Large-Area Lasing and Multicolor Perovskite Quantum Dot Patterns

TL;DR: In this article, a novel orthogonal lithography process is reported to pattern all-inorganic perovskite CsPbX3 (X = Cl, Br, I) arrays which cannot be patterned with traditional approaches.
Journal ArticleDOI
All-Inorganic Perovskite Nanocrystals with a Stellar Set of Stabilities and Their Use in White Light-Emitting Diodes.
Yajing Chang,Young Jun Yoon,Guopeng Li,Enze Xu,Shengtao Yu,Cheng-Hsin Lu,Zewei Wang,Yanjie He,Chun Hao Lin,Brent K. Wagner,Vladimir V. Tsukruk,Zhitao Kang,Naresh N. Thadhani,Yang Jiang,Zhiqun Lin +14 more
TL;DR: The judicious encapsulation of perovskite NCs into organic salts represents a facile and robust strategy for creating high-quality solid-state luminophores for use in optoelectronic devices.
