摘要

•• A novel fluorescent probe based on Ag2S QDs/g-C3N4 composites was developed to detect nitrofurazone (NFZ) sensitively.•• Excellent recognition ability could reach as low as 0.054 μM.••The detection mechanism based on formation of non-fluorescent ground state complex was demonstrated.•• The fluorescent probe has been successfully applied to detect NFZ in real water samples.
