摘要：

In this study, we aimed to synthesis of Fe -doping green fluorescent carbon dots (G -CDs) through the coelectrolysis of chrysoidine G and potassium ferrocyanide for Cr(VI) detection. The use of potassium ferrocyanide improves the quantum yield and sensing performance of G -CDs toward Cr(VI). The G -CDs have a maximum excitation wavelength of 308 nm and an emission wavelength of 510 nm. Comprehensive analyses including Raman, FT-IR, and XPS provided insights into the chemical structure and composition of the G -CDs. Under optimal conditions, G -CDs demonstrated concentration -dependent quenchin...
