Abstract Photoluminescent carbon dots (CDs) have greatest potential in fluorescence sensing, energy, bioimaging and environmental pollutant sensing. Heteroatom doping dramatically enhanced fluorescent properties stability of CDs. In this work, sulfur doped (DCDs) using jaggery as precursor through direct heating method at 180 °C. The synthesized DCDs were characterized XRD, FTIR, XPS, TEM, Fluorescence UV‐Visible spectroscopic techniques. 9 nm particle size with amorphous nature surface decorated −OH, C−S, C=O functional groups on because contribution major element like C, O, S elements. showing bright blue emission having 360 excitation 460 wavelength. Further, the employed for metal ion sensing it selectively detects Fe 3+ 1.92 μg/mL detection 5.84 limit quantification. experiment follows static quenching mechanism which is confirmed by life time experiment. This low‐cost, effective sensitive application pollution control, biomedical forensic applications.
