Achieving High Afterglow Brightness in Organic Dopant‐Matrix Systems

Advanced Optical Materials, 2021
AbstractAfterglow brightness upon ceasing excitation represents an important parameter for afterglow material applications, while purely‐organic room‐temperature afterglow materials with high quantum yields, long emission lifetimes, and strong absorption capability, which are necessary to realize high afterglow brightness, remain rarely reported. Using

Multi‐Level Confinement Single‐Molecule Charge Transfer Activated PRET for Near‐Infrared Targeted Cell Imaging

Advanced Science, EarlyView.
The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Photo‐Responsive Room‐Temperature Phosphorescent Films Exhibiting Photochromism and Time‐Dependent Phosphorescent Colors for Multilevel Anti‐Counterfeiting

Advanced Science, EarlyView.
A series of photo‐responsive polymers are prepared by a facile one‐pot in situ synthesis strategy, where RTP modules and photochromic units are systematically integrated into one polymer system. The triplet‐singlet Förster resonance energy transfer (TS‐FRET) between the donor and acceptor enables the material to exhibit time‐dependent phosphorescence ...

Importance of evaluating the intensity dependency of the quantum efficiency : impact on LEDs and persistent phosphors [PDF]

, 2018
The quantum efficiency is a key metric in lighting technology and for the quantification of luminescent processes, indicating how many photons are emitted with respect to the number of absorbed photons. Ideally, this value should approach unity to reduce
