摘要

本工作旨在研究荧光石墨烯的荧光机理，并评价荧光石墨烯基环氧复合涂料在3.5 wt% NaCl环境下的电化学性能。制备了一种石墨烯/稀土复合杂化材料，使其具有荧光性质。通过浓度梯度实验，有效缓解了石墨烯引起的荧光猝灭效应，优化了石墨烯/稀土复合杂化材料的荧光性能。电化学阻抗谱（EIS）分析表明，该涂层具有较高的电荷转移电阻、最低的断点频率和接近1的n值，具有较好的耐蚀性。该研究拓宽了石墨烯的功能应用领域，展示了其在荧光成像和防腐领域的巨大潜力。

Rare earth complex functionalized graphene: Fluorescence mechanism and electrochemistry

This work aims to investigate the fluorescence mechanism of fluorescent graphene and to evaluate the electrochemical performance of fluorescent graphene-based epoxy composite coatings in a 3.5 wt% NaCl environment. A graphene/rare-earth complex hybrid material was prepared, thereby endowing the graphene with fluorescence properties. Through concentration gradient experiments, the fluorescence quenching effect caused by graphene was effectively mitigated, optimizing the fluorescence performance of the graphene/rare-earth complex hybrid material. Electrochemical impedance spectroscopy (EIS) analysis demonstrates that the coating exhibits superior corrosion resistance, as evidenced by the highest charge transfer resistance, the lowest breakpoint frequency, and an n value approaching unity. This study broadens the functional applications of graphene, demonstrating its great potential in fluorescence imaging and corrosion protection fields.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
