TL;DR: This work provides a systematic framework for preparing highly luminescent CsPbX3 nanocrystals with variable compositions and dimensionalities, thereby improving the fundamental understanding of these materials and informing future synthetic and post-synthetic efforts toward trap-free CspbX2 nanocrystal efforts.

TL;DR: The results demonstrate that Cs2AgBiX6 (X = Cl, Br) nanocrystals are a useful model system to study structure-function relationships in the search for stable nontoxic halide perovskites.

TL;DR: A promising alternative suggested from bulk studies is the family of double p... perovskites as mentioned in this paper, which have properties similar to CsPbX3 perovsites and can be used for halide nanomaterials.

TL;DR: Investigation of visible light sensitized reduction of CO2 at Cu nanoparticles in aqueous solution by rapid-scan ATR FT-IR spectroscopy allowed structural identification of a one-electron intermediate and demonstrated its kinetic relevancy for the first time.

TL;DR: This report designs and synthesizes deep blue emitting, quantum confined, perovskite nanoplates and analyzes their optical properties by combining angular emission measurements with back focal plane imaging and correlating the results with physical characterization, and introduces a valuable method to extend the efficiencies and applications of perovkite based photonic devices beyond those based on current materials.
