TL;DR: The origins of the significantly blue-shifted emission from CsPbBr3 nanocrystals and the synthetic strategies toward fabrication of stable perovskite nanocrystal materials with emission in the red and infrared parts of the optical spectrum are discussed, related to fabrication of mixed cation compounds guided by Goldschmidt tolerance factor considerations.

TL;DR: By introducing a thin film of perfluorinated ionomer (PFI) sandwiched between the hole transporting layer and perovskite emissive layer, the device hole injection efficiency has been significantly enhanced and the three-fold increase in peak brightness reaching 1377 cd m(-2).

TL;DR: Emission color controlled, high quantum yield CH3NH3PbBr3 perovskite quantum dots are obtained by changing the temperature of a bad solvent during synthesis to achieve good spectral purity and short radiative lifetimes.

TL;DR: Stable solid-state perovskite based luminophores with different emission colors via surface protection of CsPbX3 (X = Br or I) with a polyhedral oligomeric silsesquioxane are presented.

TL;DR: In this article, a review of recent developments in the direct synthesis and ion exchange-based reactions leading to hybrid organic and all-inorganic lead halide perovskite nanocrystals is presented, and optical properties related to quantum confinement effects, single particle emission and lasing are considered.
