Ultralong persistent luminescence from carbon dots
Seunghyup Yoo, Young‐Jin Song, Sangin Hahn
Abstract
Hour-level persistent luminescence is realized with carbon dots embedded in cyanuric acid, the composition of which is easily obtained by the microwave-assisted heating of carbon dots and urea. By forming donor-acceptor blends, the proposed composition yields intermediate states with long lifetimes, providing a rare-earth-metal-free route to ultralong persistent luminescence.
