摘要

石墨烯量子点是一种具有独特物理和化学特性的准零维纳米材料。本研究利用太赫兹时域光谱系统分析了不同浓度的石墨烯量子点对太赫兹波的吸收特性。此外，我们还施加了电场和磁场，以更详细地探索石墨烯量子点的太赫兹波吸收特性。结果表明，石墨烯量子点的太赫兹吸收率与样品浓度和外加电场强度呈正相关。然而，它与外加磁场强度呈负相关。这项工作结合了太赫兹技术和微流控装置，为深入研究石墨烯量子点提出了一种可行的方法。

Study on the Terahertz Spectroscopy Properties of Graphene Quantum Dots Based on Microfluidic Chip

Graphene quantum dots are quasi-zero-dimensional nanomaterials with unique physical and chemical properties. This study utilized a terahertz (THz) time-domain spectroscopy system to analyze the absorption characteristics of THz-waves by graphene quantum dots at different concentrations. Additionally, we applied electric fields and magnetic field to explore the THz-wave absorption properties of graphene quantum dots in greater detail. The results indicate that the THz absorbance of graphene quantum dots is positively correlated with sample concentration and applied electric field strength. However, it is negatively correlated with the intensity of the applied magnetic field. This work combines THz technology and microfluidic devices to propose a viable methodology for conducting in-depth study on graphene quantum dots.
