In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...

Synthesis of Novel Stable ZnSe Magic‐Sized Clusters and Their Direct Transformation to Quantum Dots
We have developed a low‐temperature synthetic approach that enables the fabrication of novel ZnSe MSCs with remarkable thermal stability. These stabilized MSCs serve as efficient precursors that can be readily converted to ZnSe QDs under mild conditions through simple introduction of a selenium source.

This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

A dual hard‐base anchoring strategy was developed to synthesize ZnSe@ZnS:Eu3+ quantum dots, leveraging fluoride‐oleylamine interactions to create surface atomic Eu doping sites. By precisely tuning temperature, Eu3+ concentration, and fluoride levels, we obtain morphologies ranging from tip growth to coupled flower‐like structures.

Thin‐shell InAs/ZnSe quantum dots functionalized with metal chalcogenide ligands were employed as electron transport layers in organic optoelectronic devices, yielding optimized conduction band alignment and film morphology. Consequently, the devices achieved enhanced charge transport, a detectivity of ∼1013 Jones, and a power conversion efficiency of ...

Three-photon absorption in ZnSe and ZnSe/ZnS quantum dots
ZnSe and ZnSe/ZnS core/shell quantum dots (QDs) of two different sizes (4.5 and 3.5 nm) have been synthesized. The nonlinear absorption is measured at 1064 nm using a 35 ps laser with an open aperture Z-scan setup.
