摘要

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.
