Efficient Photocatalytic Hydrogen Evolution Enabled by Defect‐ and Interface‐Induced Dual Built‐in Electric Fields in a ZnIn2S4/1T‐2H WS2 Heterojunction

Small, EarlyView.
An N, Sv‐ZnIn2S4/1T‐2H WS2 composite photocatalyst is constructed via an in situ hydrothermal‐solvothermal strategy, simultaneously forming a defect‐induced p‐n homojunction in ZnIn2S4 and a type‐II heterojunction with hybrid 1T/2H WS2. The coupled dual built‐in electric fields promote charge separation and direct photoexcited electrons toward sulfur ...

Mechanical Alloying and Concentration Quenching of the Luminescence of Pr³⁺ Ions in Chalcogenide Glass

Solids
The disadvantage of chalcogenide glasses containing rare earth ions as luminescent materials for the IR optical range is the strong concentration quenching of luminescence due to the non-uniform distribution of rare earth ions in the glass matrix.

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
