White Light Emission and Energy Transfer in Mixed‐Metal Europium/Terbium/Thulium Formate Metal–Organic Frameworks: Effect of Lanthanum Dilution

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

Advanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.

Effect of Alkyl Chain Length on the Bandgap, Ferroelectric, and Photoelectric Properties of Lead‐Based Molecular Ferroelectrics

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study develops a novel 2D molecular ferroelectric [C6N2H18]PbI4 with polarization enhanced photovoltaics. It systematically investigates the effect of alkylamine spacer cation chain lengths on the band gap, ferroelectric, and photoelectric properties, offering new design strategies.

Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

Advanced Science, Volume 13, Issue 43, 3 August 2026.
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.

Halide/Pseudohalide Anion Regulation of Polar Structure and Glass‐Forming Ability Toward Polar Hybrid Glass‐Ceramic

Aggregate, Volume 7, Issue 8, August 2026.
Systematic anion engineering from halide to pseudohalide (Cl− → Br− → I− → NCS−) in a family of cadmium(II)‐based organic‐inorganic hybrids drives a progressive transition from centrosymmetric to polar structure, depresses melting point, reduces fragility index, and enhances glass‐forming ability, ultimately affording a polar hybrid glass‐ceramic with ...
