Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

Laser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

Modular Polymers With Tuneable Charge and Amphiphilicity for Effective Antimicrobial Photodynamic Therapy

Macromolecular Rapid Communications, EarlyView.
A modular dual‐strategy platform combining free radical copolymerisation and post‐polymerisation modification yields a library of ruthenium‐functionalised polymers for antimicrobial photodynamic therapy. Tuneable composition and net charge govern activity against multidrug‐resistant Pseudomonas aeruginosa biofilms and Staphylococcus aureus under ...

Molecular Persistent Room-Temperature Phosphorescence from Tetraarylaminoboranes

Herein, we report the synthesis, molecular structure, and optical features of tetrarylaminoboranes 1 (Mes2B-N­(Ph)­(C10H7)) and 2 (Mes2B-N­(Ph)­(C14H9)). In the solution state, 1 shows aggregation-induced emission enhancement and color switching, while 2

Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...
