TL;DR: It is suggested that single-crystal perovskite nanostructures provide improved photophysical properties that are important for fundamental studies and future applications in nanoscale optoelectronic and photonic devices.

TL;DR: The case for the utility and advantages of chemically synthesized QDHs for solar energy conversion are presented, beginning with an overview of various methods of heterostructured material synthesis and a survey of heretofore reported materials systems.

TL;DR: Time-resolved photoluminescence, transient reflection spectroscopy, and electrical transport measurements show that the CsPbBr3 epitaxial thin film has a slow charge carrier recombination rate, low surface recombination velocity, and low defect density of 1012 cm-3, which are comparable to those of cesium lead bromide perovskite single crystals.

TL;DR: In this article, the use of long-chain ammonium additives during thin film deposition as surface capping ligands results in the stabilization of metastable bulk all-inorganic cesium lead iodide (CsPbI3) perovskite phases without alloying mixed cations or anions.

TL;DR: In this paper, a technique of selective laser excitation has been developed and used to study the optical spectrum of the charge compensated sites in CaF2:Er3+, which allows unambiguous interpretation and classification of the spectral lines observed from crystals with multiple sites.
