TL;DR: In this article, the solvent-related effect on phase formation in CsBr-PbBr2 system through single crystal X-ray diffraction measurement is investigated thoroughly, and it is found that the prepared product is dominantly determined by the coordination number (CN) of Pb(II) and the ratio of precursors.

TL;DR: A room-temperature colloidal synthesis of few-unit-cell-thick CsPbBr3 QWs with lengths over a hundred nanometers with surfactant-directed oriented attachment growth mechanism was reported, and the dependence of the bandgap on the diameter with different numbers of unit cells was presented for the first time.

TL;DR: Quantitative synchrotron radiation X-ray diffraction analysis and transient spectroscopic measurements point out that large lattice strain existing in CsPbBr3 nanoparticles induces more crystal defects and thus decreases the PLQY, implying that lattices strain is a key factor other than the surface defect to dominate thePLQY of colloidal photoluminesence materials.

TL;DR: The first experimental evidence is presented to demonstrate that the strain is a crucial factor in tuning the energy splitting of the bright and dark excitons, resulting in different PL properties.

TL;DR: In this paper, the authors used an Al-doped ZnO (AZO) as inserting layer between the znO and Ag cathode to improve the performance of green perovskite light emitting diodes (PeLEDs) with ITO/NiO/CsPbBr3 QDs.
