Solution‐processed perovskite‐based light‐emitting diodes (PeLEDs) are promising candidates for low‐cost, large‐area displays, while severe deterioration of the perovskite light‐emitting layer occurs during deposition of electron transport layers from solution in an issue. Herein, core/shell ZnO/ZnS nanoparticles as a solution‐processed electron transport layer in PeLED based on quasi‐2D PEA2Csn−1...
The therapeutic potential of nanomaterials toward oxidative damage relevant diseases has attracted great attentions by offering promising advantages compared with conventional antioxidants. Although different kinds of nanoantioxidants have been well developed, the facile fabrication of robust and efficient nanoscavengers is still met with challenges like the use of toxic and high‐cost subunits, the...
Although excellent performance such as high efficiency and stability have been achieved in quantum dot (QD)‐based light‐emitting diodes (QLEDs) possessing an organic/inorganic hybrid device structure, the highly expected all‐inorganic QLEDs remain at the bottleneck stage in recent years, resulting from the luminance quenching of QDs caused by inorganic hole transport layer (HTL) and unbalanced charge...
Lithium–sulfur (Li–S) batteries are investigated intensively as a promising large‐scale energy storage system owing to their high theoretical energy density. However, the application of Li–S batteries is prevented by a series of primary problems, including low electronic conductivity, volumetric fluctuation, poor loading of sulfur, and shuttle effect caused by soluble lithium polysulfides. Here, a...
Here a simple and an environmentally friendly approach is developed for the fabrication of Si–void@SiOx nanowires of a high‐capacity Li‐ion anode material. The outer surface of the robust SiOx backbone and the inside void structure in Si–void@SiOx nanowires appropriately suppress the volume expansion and lead to anisotropic swelling morphologies of Si nanowires during lithiation/delithiation, which...
