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

Molecular radio afterglow probes for cancer radiodynamic theranostics

, 2023
X-ray-induced afterglow and radiodynamic therapy tackle the tissue penetration issue of optical imaging and phototherapy. However, inorganic nanophosphors used in this therapy have their radio afterglow dynamic function as always on, limiting the ...

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

Small, EarlyView.
A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.
