Abstract

An “on–off” fluorescence sensing system was constructed with g-CNQDs@p-acetaminophenol for detection of Cr3+. g-CNQDs were synthesized, and the fluorescence signal was enhanced based on the effect between APAP and g-CNQDs. The introduction of Cr3+ into the system results in fluorescence quenching.
