We report a simple and versatile approach to creating highly transparent superhydrophobic surface with dual-scale roughness on the nanoscale. 3-Aminopropyltrimethoxysilane (APTS)-functionalized silica nanoparticles of two different sizes (100 20 nm) were sequentially dip coated onto substrates, followed by thermal annealing. After hydrophobilization nanoparticle film (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trichlorosilane for 30 min or longer, became an advancing water contact angle greater...
Abstract A stretchable, flexible, and bendable random laser system capable of lasing in a wide range spectrum will have many potential applications next‐ generation technologies, such as visible‐spectrum communication, superbright solid‐state lighting, biomedical studies, fluorescence, etc. However, producing an appropriate cavity for spectral remains challenge owing to the rigidity resonator coherent loops. 2D materials with wrinkled structures exhibit superior advantages high...
We report a simple, robust, and inexpensive strategy to enable all-inorganic CsPbX3 perovskite nanocrystals (NCs) with set of markedly improved stabilities, that is, water stability, compositional phase segregation stability via impregnating them in solid organic salt matrices (i.e., metal stearate; MSt). In addition acting as matrices, MSt also functions the ligand bound surface NCs, thereby eliminating potential damage NCs commonly encountered during purification copious past work. Quite...
Dual-functional devices that can simultaneously detect light and emit have a tremendous appeal for multiple applications, including displays, sensors, defense, high-speed optical communication. Despite the efforts of scientists, progress integration phototransistor, where built-in electric field separates photogenerated excitons, light-emitting diode, radiative recombination be enhanced by band offset, into single device remains challenge. Combining superior properties perovskite quantum...

Abstract Application of lasers is omnipresent in modern‐day technology. However, preparation a lasing device usually requires sophisticated design the materials and costly, which may limit suitable choice wavelengths. Random lasers, on other hand, can circumvent aforementioned shortcomings with simpler fabrication process, lower processing cost, material flexibility for any wavelengths threshold, providing roadmap super‐bright lighting, displays, Li‐Fi, etc. In this work, ultralow‐threshold...
Despite impressive recent advances in the synthesis of lead chalcogenide solid nanoparticles, there are no examples hollow nanoparticles (HNPs) with controlled diameter and shell thickness as current synthetic approaches for HNPs have inherent limitations associated their complexity, inability to precisely control dimensions, limited possibilities regard applicable materials. Herein, we report on an unconventional strategy crafting uniform (PbS PbTe) tailorable size, surface chemistry,...
The photovoltaic performance of perovskite solar cells is enhanced by interfacing with rationally designed CsPbBr<sub>x</sub>I<sub>3−x</sub> quantum dots.
Two-dimensional (2D) material nanocomposites have emerged as a system for discovering new physical phenomena and developing novel devices. However, because of the low density states most two-dimensional materials such graphene, heterostructure suffers from an enhanced depletion region, which can greatly reduce efficiency charge carrier transfer deteriorate device performance. To circumvent this difficulty, here we propose alternative approach by inserting second 2D mediator with heavy...
