Host Surface-Induced Excitation Wavelength-Dependent Organic Afterglow

Journal of the American Chemical Society, 2023
The design and construction of organic afterglow materials is an attractive but formidably challenging task due to the low intersystem crossing efficiency and nonradiative decay. Here, we developed a host surface-induced strategy to achieve excitation wavelength-dependent (Ex-De) afterglow emission through a facile dropping process.

Organic Afterglow Nanoparticles in Bioapplications

Chemistry – A European Journal, 2023
AbstractOrganic afterglow nanoparticles are unique optical materials that emit light long after cessation of excitation. Due to their advantages of no need for real‐time light excitation, avoiding autofluorescence, low imaging background, high signal‐to‐background ratio, deep tissue penetration, and high sensitivity, afterglow imaging technology has ...

Sonication‐Responsive Organic Afterglow Emulsions

Advanced Functional Materials, 2023
AbstractIn contrast to their fluorescence counterparts, stimuli‐responsive organic afterglow materials display distinct advantages to function normally in the presence of strong fluorescence background. However, most of the stimuli‐responsive afterglow materials can only work in their solid states with those in aqueous medium being rarely reported.

Anti‐Smudge Organic Afterglow Panels

Advanced Functional Materials
AbstractOrganic afterglow panels show promising applications in display and information anti‐counterfeiting. Like other panels, organic afterglow panels are susceptible to contamination when used, which can affect their aesthetics and clarity. Here, a kind of visible‐light‐excitable anti‐smudge organic afterglow panels based on a dopant‐matrix strategy

Excited State Modulation for Organic Afterglow: Materials and Applications

Advanced Materials, 2016
Organic afterglow materials, developed recently by breaking through the difficulties in modulating ultrafast‐decayed excited states, exhibit ultralong‐lived emission for persistent luminescence with lifetimes of several orders of magnitude longer than traditional fluorescent and phosphorescent emissions at room temperature. Their exceptional properties,

TADF‐Type Organic Afterglow

Angewandte Chemie International Edition, 2021
AbstractWe report a highly efficient dopant‐matrix afterglow system enabled by TADF mechanism to realize afterglow quantum yields of 60–70 %, which features a moderate rate constant for reverse intersystem crossing (kRISC) to simultaneously improve afterglow quantum yields and maintain afterglow emission lifetime.
