TL;DR: It is demonstrated that carrier multiplication commences at the threshold excitation energy near the energy conservation limit of twice the band gap, and has step-like characteristics with an extremely high quantum yield of up to 98%.

TL;DR: A successful encapsulation of colloidal perovskite nanocrystals within solid-lipid structures mainly consisting of stearic acid is reported on, boosting the potential applications of all-inorganic perovSKite Nanocrystals for ink-printing.

TL;DR: In this article, the authors demonstrate nonradiative energy transfer for colloidal CsPbBr3 nanocrystals using time-resolved optical characterization of purposefully prepared batches of nanocrystal with different sizes.

TL;DR: This work establishes an intimate relation between quantum dot size and even shape and its bandgap energy on a single object level and shows the presence of an effective coupling between proximal dots in an ensemble, leading to band structure modification.

TL;DR: In this paper, the authors showed that the ability of a semiconductor to create several electron-hole pairs from the absorption of a single photon whose energy exceeds the material's bandgap is potentially important for improving the efficiencies of devices like solar cells and photodetectors.
