Multicolor room-temperature phosphorescent carbon dots for information encryption prepared by modifying the amino substitution sites of precursors.
Carbon dots (CDs), an emerging class of carbon-based nanophosphors, have been regarded as ideal candidates for realizing long-afterglow room-temperature phosphorescence (RTP) owing to their exceptional optical properties, low cost, low toxicity, and high stability. In this study, three room-temperature phosphorescent c...
