Abstract Perovskites have emerged as a class of cutting‐edge photovoltaic and light‐emitting materials. However, poor stability due to high moisture sensitivity undesirable blinking severely limits their further application. Here, solve these problems without destroying optoelectronic performance, simple process for the fabrication nonblinking CsPbBr 3 quantum dots (QDs) is investigated. By embedding QDs into waterless silica spheres, can be strikingly suppressed, with an effective...
Abstract Rational surface engineering of metal–organic frameworks (MOFs) provide potential opportunities to address the sluggish kinetics oxygen evolution reaction (OER). However, development MOF‐based materials with low overpotentials remains a great challenge. Herein, post‐synthesis strategy prepare highly efficient pre‐electrocatalysts via all‐solid‐phase mechanochemistry is demonstrated. The Fe‐based MOF (MIL‐53) can be reconstructed and anchored atomically dispersed Ni/Co sites. As...
Abstract In recent years, metal‐halide perovskite quantum dots (QDs) have been broadly applied in optoelectronic fields due to their fascinating characteristics, such as high photoluminescence yields, tunable bandgaps, and low‐cost solution processing. Here, a facile ligand‐exchange strategy is employed for the fabrication of CsPbBr 3 QDs capped with di‐dodecyl dimethyl ammonium bromide. It demonstrated that treated QDs' film becomes more compact higher electron mobility shorter lifetime....
Emergent collective modes in lattices give birth to many intriguing physical phenomena condensed matter physics. Among these modes, large-area typically feature small-level spacings, while a mode with stable frequency tends be spatially tightly confined. In this Letter, we theoretically propose and experimentally demonstrate symmetry-related topological corner tunable area frequency. This emerges from the hybridization of homogeneous Dirac point in-gap modes. Remarkably, hybridized possesses...
Novel CsPbBr3/CdS core/shell structure quantum dots (QDs) were successfully synthesized using a facile hot-injection method. The corresponding QDs based light-emitting diodes (QLEDs) further prepared, which demonstrated the maximum luminance of 354 cd/m2 and an external efficiency (EQE) 0.4% with current (CE) 0.3 cd/A. Moreover, optoelectronic performance QLEDs exhibited comparable enhancement in contrast to pure CsPbBr3 QLEDs. Hypothetically, novel introduced one new route for advanced...
Abstract Although high‐voltage positive electrode materials for high energy density lithium‐ion batteries have gained a great attention, the lack of compatible electrolytes with sufficiently oxidative stability to deliver an excellent cycling ability restricts their practical application. Fluorinated solvents are considered as promising candidates electrolyte solvents. In this study, we select 1,1,2,2‐tetrafluoroethyl‐2,2,3,3‐tetrafluoropropyl ether (TTE) boiling point, low cost, and good...
2D/3D mixed perovskites have been recognized as very promising materials for simultaneously achieving high efficiency and stability in solar cells.
Currently, the authentication of virgin walnut oil (VWO) has become very important due to possible adulteration VWO with cheaper plant oils such as soybean (SO), puer tea seed (PO), and sunflower (SFO). Methods involving Fourier transform infrared (FT-IR) spectroscopy combined chemometric techniques (partial least square) were developed for quantification SO, PO, SFO in VWO. IR spectra samples recorded at frequency regions 4000–650 cm −1 on horizontal attenuated total reflectance (HATR)...

High-quality perovskite films are beneficial for fabricating solar cells (PSCs) with excellent photoelectric performance. The substrate on which the film grows plays a profound role in improving crystallization quality of film. Here, we proposed novel method optimizing CsPbI3 films, that is, two-dimensional (2D) substrate-assisted growth (2D-PSAG) method. prepared PEA2PbI4 2D proper wettability and roughness is used as to fabricate high-quality Moreover, it found PEA cations show vertical...
