Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

FlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Rigid polymer matrix enables direct red afterglow from rhodamine dyes without energy transfer

FlexMat, EarlyView.
This work presents a universal and facile strategy to achieve direct red room‐temperature phosphorescence from commercial rhodamine dyes by harnessing the superior rigid confinement of a novel phosphorus‐containing polymer (DOBP), effectively bypassing the complex TS‐FRET process.

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 ...

Structural and Spin–Orbit Coupling Synergy Enables Tunable Afterglow in Cytosine‐Based Hybrid Materials

Laser &Photonics Reviews, EarlyView.
Zero‐dimensional organic–inorganic hybrid materials (Cyt)2ZnX4·H2O (X = Cl, Br) were synthesized using cytosine (Cyt) and zinc halides, enabling effective regulation of room‐temperature phosphorescence (RTP) through halogen substitution in the inorganic [ZnX4]2− unit.

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
