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.

Fluorescence Tuning of Carbon Dots from Red to Blue via UV‐Induced Photochemical Etching

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A UV‐driven photochemical process enables continuous color evolution of carbon dots from red to blue using a single irradiation parameter. Progressive photoetching restructures graphitic domains and surface states, allowing full visible‐spectrum emission control.

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 ...

Self‑Protective Carbonized Polymer Dots Enabling Ultralong Room‑Temperature Phosphorescence in Strong and Tough Flexible Gels

Aggregate, Volume 7, Issue 8, August 2026.
The trade‐off between intersystem crossing and triplet exciton stabilization in PVA‐based self‐protective CPDs is resolved by tuning the alcoholysis degree of PVA. Using PVA with 88% alcoholysis affords NCD88 with an ultralong RTP lifetime of 1.05 s.

Lighting up FLASH and beyond: TLD response across four orders of magnitude in proton dose rate

Medical Physics, Volume 53, Issue 8, August 2026.
ABSTRACT Background Thermoluminescent dosimeters (TLDs) are widely used for proton therapy dosimetry and remote audits. Yet their response under pulsed delivery and the ultrahigh dose rates relevant to proton FLASH remains incompletely characterized.
