Blue‐Emitting ZnSe(Te) Quantum Dots and Light‐Emitting Diodes

open access: yesAdvanced Science, EarlyView.
 . ABSTRACT Zn‐based quantum dots (QDs) have been regarded as the most promising Cd‐free candidates for blue‐emitting applications. ZnSe QDs exhibit an ultra‐narrow full width at half maximum (FWHM), high photoluminescence quantum yield (PLQY), and excellent environmental stability, making them ideal for blue‐violet emitters.

Functional Group Effects on the HOMO⁻LUMO Gap of g-C₃N₄.

open access: yesNanomaterials (Basel, Switzerland)
Graphitic carbon nitride (g-C₃N₄) is a promising semiconductor material which has been widely studied in nanoscience. However, the effect of modifying the performance of g-C₃N₄ is still under debate. In this communication, we show the size and functional group effects on the g-C₃N₄ using density functional theory (DFT) calculations. It was found that a

Electronic‐State Polarization Engineering‐Regulated Fluorinated Covalent Organic Framework Nanocables for Fast Lithium‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Electronic‐state polarization engineering is realized by constructing fluorinated COF nanocables on conductive CNTs scaffolds. The polar C─F units generate localized electric fields and strong ion‐dipole interactions, promoting Li+ adsorption and transport.

Intermolecular Aggregation‐Induced Delayed Fluorescence Scintillators for Ultrahigh‐Resolution X‐Ray Imaging

open access: yesAdvanced Science, EarlyView.
An intermolecular AIDF strategy enables an organic X‐ray scintillator (OXST) that resists concentration quenching and efficiently utilizes singlet and triplet excitons. The AIDF emitter, embedded in a polysulfone matrix, yields bright, flexible, and transparent scintillation screens with ultralow detection limits and high spatial resolution, offering a

Electrostatic Potential Complementarity for Thickness‐Tolerant Cathode Interlayers in High‐Efficiency Organic and Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
Two model molecules — trimesic acid (TMA) and phloroglucinol (PG) — with opposite central electrostatic potential (ESP) distributions are employed to elucidate how molecular electrostatic interactions regulate the cathode interlayer (CIL) PDINN. Electrostatic potential complementarity is revealed as the intrinsic origin of thickness sensitivity in CILs,

Synergistic Organic–Inorganic Interface Engineering for Stable Zinc Metal Anodes in Aqueous Batteries

open access: yesAdvanced Science, EarlyView.
A multifunctional mercaptosuccinic acid enables an ultrathin organic–inorganic SEI (Zn‐S‐RCOOH) that synergistically regulates interfacial water and accelerates Zn2+ transport. The optimized hydrogen‐bond environment and ZnS‐guided deposition suppress dendrites, corrosion, and by‐product formation, delivering ultrastable Zn cycling and high‐performance

One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

open access: yesAdvanced Science, EarlyView.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...
