摘要
以间苯二胺和磷酸为原料，采用水热法合成了一种高荧光量子产率（67.53%）的氮、磷掺杂碳点（N，P-CDs），对其合成条件（反应时间和温度）进行了优化。采用红外光谱、紫外吸收光谱、荧光光谱、光电子能谱对N，P-CDs的结构和光学性能进行了表征，并用透射电镜对其形貌进行了观察。结果显示N，P-CDs呈球形，平均粒径约为7.5 nm，在365 nm紫外光激发下发出亮绿色荧光，最大激发与发射波长分别为442 nm和515 nm。将N，P-CDs应用于金属离子检测中，发现其对Pd,2+,具有良好的选择性，检测限为0.995 μmol/L。通过紫外吸收光谱、荧光寿命的测定研究了Pd,2+,对N，P-CDs的荧光猝灭机制，结果表明猝灭机制为静态猝灭，分析是因为Pd,2+,与N，P-CDs形成了复合物。
Abstract
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.
