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
Dual-Phase CsPbBr3–CsPb2Br5 Perovskite Thin Films via Vapor Deposition for High-Performance Rigid and Flexible Photodetectors
Guoqing Tong,Guoqing Tong,Huan Li,Danting Li,Zhifeng Zhu,Enze Xu,Guopeng Li,Linwei Yu,Jun Xu,Yang Jiang +9 more
TL;DR: Tetragonal CsPb2 Br5 provides satisfactory passivation to reduce the recombination of the charge carriers, and with its lower free energy, it enhances the stability of the inorganic perovskite devices.
Journal ArticleDOI
Solvent‐Polarity‐Engineered Controllable Synthesis of Highly Fluorescent Cesium Lead Halide Perovskite Quantum Dots and Their Use in White Light‐Emitting Diodes
Guopeng Li,Hui Wang,Ting Zhang,Longfei Mi,Yugang Zhang,Zhongping Zhang,Wenjun Zhang,Yang Jiang +7 more
TL;DR: In this paper, the synthesis of CsPbX3 (X = Cl, Br, I, or mixed Cl/Br and Br/I) by direct ion reactions in ether solvents is reported, and for the first time the synergetic effects of solvent polarity and reaction temperature on the nucleation and growth of QDs are demonstrated.
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
