Abstract

A novel, simple but highly selective fluorescent probe is developed for the direct detection of sulfide ions [S²⁻] based on the fluorescence quenching of the functionalized CdS QDs in aqueous solution at trace levels and successfully applied for quantitation of S²⁻ from water samples in a complex matrix exclusive of pretreatment by standard addition method.
