Abstract

The effective use of polymer carbon dots (PCD) in various fields of science and technology requires a more detailed understanding of the mechanisms of their photoluminescence formation and change as a result of their interaction with the environment. In this study, PCD synthesized via a hydrothermal method from citric acid and ethylenediamine are studied in various solvents using FTIR spectroscopy, optical absorption spectroscopy, and photoluminescence spectroscopy. As a result of the analysis of the obtained dependencies of such PCD spectral characteristics as the photoluminescence FWHM, the photoluminescence quantum yield, the photoluminescence lifetime on the acidity and basicity of the solvent, a hypothesis was formulated on the formation mechanism of hydrogen bonds between the PCD surface groups and the molecules of the environment, and conclusions were made about the donor-acceptor nature of the synthesized PCD.

摘要

要在各种科学技术领域有效利用聚合物碳点（PCD），需要更详细地了解其光致发光形成机制以及与环境相互作用导致的变化机制。在本研究中，使用傅里叶变换红外光谱（FTIR）、光吸收光谱和光致发光光谱，对通过水热法由柠檬酸和乙二胺合成的PCD在各种溶剂中进行了研究。通过分析PCD光谱特性（如光致发光半高宽、光致发光量子产率、光致发光寿命）与溶剂酸碱度之间的依赖关系，提出了关于PCD表面基团与环境分子之间氢键形成机制的假设，并对合成的PCD的供体 - 受体性质得出了结论。
