Synthesis of Nitrogen and Phosphorus Doped Carbon Dots and Their Application in Pd2+ Sensing
The high fluorescence quantum yield(67.53%) nitrogen and phosphorus-doped carbon dots(N, P-CDs) were synthesized by hydrothermal method using m-phenylenediamine and phosphoric acid as the main raw materials and the synthesis conditions(reaction time and temperature) have been optimized. The structure and optical properties of N, P-CDs were characterized by FT-IR, ultraviolet absorption spectroscopy, fluorescence spectroscopy, and X-ray photoelectron spectroscopy, and their morphology was observed by transmission electron microscopy. The results show that N, P-CDs are spherical, with an average particle size of about 7.5 nm, and emit bright green fluorescence under 365 nm ultraviolet light excitation. The maximum excitation and emission wavelengths are 442 nm and 515 nm, respectively. The application of N, P-CDs to the detection of metal ions indicated that they displayed good selectivity to Pd,2+, and the detection limit is 0.995 μmol/L. The fluorescence quenching mechanism of Pd,2+, on N, P-CDs was studied by UV absorption spectroscopy and fluorescence lifetime measurement. The results showed that the quenching mechanism was static quenching, which is due to the formation of complexes between Pd,2+, and N, P-CDs.
