ABSTRACT Herein, a kind of N‐doped fluorescent carbon dots (N‐CDs) were prepared by using melamine and carboxymethyl cellulose (CMC) as precursors through straightforward hydrothermal method. The designed sensor displayed uniform nanoscale distribution, excellent hydrophilicity, strong fluorescence emission with quantum yield 37.98%. Moreover, the N‐CDs could be utilized for Fe 3+ detection “On–Off” transition via mechanism internal filtration effect (IFE) static quenching process. Two good linear relationships within concentrations from 10 to 100μM 100 500 μM obtained, which indicated that quantitative analysis calculated limit (LOD) was 0.510 (3σ/slope). Additionally, used in solid phase based on strategy, is promising anticounterfeiting application.
