TL;DR: Time-resolved optical second harmonic generation was used to observe hot-electron transfer from colloidal lead selenide nanocrystals to a titanium dioxide electron acceptor, which occurred much faster than expected and excited coherent vibrations of the TiO2 surface atoms, which could be followed in real time.

TL;DR: A comprehensive review of metal-halide perovskite nanocrystals can be found in this article, where researchers having expertise in different fields (chemistry, physics, and device engineering) have joined together to provide a state-of-the-art overview and future prospects of metalhalide nanocrystal research.

TL;DR: The results demonstrate the versatility of colloidal perovskite nanoplatelets as a material platform, with tunability extending from the deep-UV, across the visible, into the near-IR.

TL;DR: Colloidal nanoplatelets with predominantly single unit cell thickness and submicron lateral dimensions are obtained, which are stable in solution and exhibit a sharp excitonic absorption feature 0.5 eV blue-shifted from that of the three-dimensional bulk MAPbBr3 phase, representing a new addition to the growing family of colloidal two-dimensional nanostructures.

TL;DR: It is shown that the ratio of lead to sulfur precursor available during nucleation is a critical parameter affecting subsequent growth and monodispersity of PbS nanocrystal ensembles, indicating an ensemble that is close to the homogeneous limit.
