O/C Ratio‐Driven Fluorescence Enhancement in Cellulose‐Derived Carbon Quantum Dots: Mechanistic Insights into Reaction Pathways

open access: yesAdvanced Science, EarlyView.
Three types of CQDs are prepared from cellulose and its derivatives via hydrothermal carbonization. An increase in the atomic O/C ratio from 0.25 to 0.61 results in a nearly seven‐fold enhancement in QY. DFT calculations verify this mechanism. Further, this study elucidates the formation pathways of cellulose‐derived CQDs and proposes a fluorescence ...

Ultrafast Photoexcitation Induced Nonthermal Lattice Expansion in 2D Perovskite

open access: yesAdvanced Science, EarlyView.
Photo‐induced lattice expansion in 2D Dion‐Jacobson (DJ) perovskites is a non‐thermal process, resulting in the more relaxed local lattice strain and the larger bandgap. It activates a self‐passivation mechanism, effectively diminishing trap state density. The synergy of these effects leads to suppressed non‐radiative recombination and prolonged charge
