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.

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 ...
