AI Article Synopsis
- Researchers developed BF2bdk-based afterglow emitters with impressive photoluminescence quantum yields of up to 46.3%.
- These emitters have long lifetimes of about 1 second, which makes them suitable for various applications.
- Key factors influencing their afterglow properties include the types of excited states, the variety of excited state forms, small energy gaps between singlet and triplet states, and strong dipole interactions.
Article Abstract
We report a systematic molecular design in BF2bdk-based afterglow emitters with photoluminescence quantum yields up to 46.3% and lifetimes around 1 s. Suitable excited-state types, diverse excited state species, relatively small singlet-triplet energy gaps and strong dipole-dipole interactions are critical in determining the afterglow properties.
