Research Article uncovers new fluorescence properties in carbon dots for information encryption and hydrogels, suggesting novel applications.
Breathing new life into a classic system. In Research Article e7943243, Patrick Théato and co-workers uncover the phenomenon of aggregation-induced emission within traditional carbon dots derived from citric acid and urea. By regulating π–π stacking and solvent interactions, tunable solvent-responsive fluorescence is achieved, broadening the system's applications in information encryption and smart fluorescent hydrogels.
