TL;DR: This work proposes and demonstrates facile solution synthesis of a series of colloidal organometal halide perovskite CH3NH3PbX3 (X = halides) nanoparticles with amorphous structure, which exhibit high quantum yield and tunable emission from ultraviolet to near-infrared in light-emitting devices.

TL;DR: In high-efficiency PeLEDs based on colloidal perovskite nanocrystals synthesized at room temperature possessing dominant first-order excitonic radiation, it is found that the Auger nonradiative recombination is effectively suppressed in low driving current density range.

TL;DR: It is demonstrated that the intrinsic band offset at the CH3NH3PbI3/MoS2 interface can be overcome by creating sulfur vacancies in MoS2 using a mild plasma treatment, and highlights the feasibility of applying defect-engineered 2-D TMDCs as charge-extraction layers in perovskite-based optoelectronic devices.

TL;DR: In this article , the steady-state microstructures and microtextures of the nanostructured α-uranium were characterized by transmission electron microscopy (TEM) and transmission Kikuchi diffraction (TKD) analysis in scanning electron microscope (SEM), respectively.

TL;DR: In this paper , surface rolling extrusion processing is applied to reconstruct the microstructure of U-5.7Nb alloy and a micro-nano structure layer is formed on the surface, at the same time the inclusions in the surface are also refined and the uniformity of niobium element distribution is improved.
