石墨烯基荧光材料作为一种基于荧光碳的纳米材料，近年来受到越来越多的关注。当石墨烯的尺寸和结构被适当控制时，石墨烯会被诱导产生光致发光，从而产生所谓的荧光石墨烯（FG）。FG具有与尺寸、缺陷和波长相关的发光发射，这与传统的基于量子点的发光类似。此外，具有优异的化学稳定性，良好的生物相容性，低毒性，上转换发射，pH敏感性和耐光漂白，FG承诺提供大量的应用在许多领域：生物成像，光致发光，传感器等，目前，研究工作已经允许FG生产的许多方法，从简单的氧化石墨烯切割碳源和有机合成的小分子。在这篇专题文章中，我们总结了已报道的荧光石墨烯，重点是它们的分类，性质，合成和应用。同时，展望了它们的发展前景，并比较了FG与其他荧光炭基材料的特点。
Fluorescent graphene-based materials, labelled as a sort of fluorescent carbon-based nanomaterial, have drawn increasing attention in recent years. When the size and structure of graphene were controlled properly, photoluminescence was induced in graphene, resulting in the so-called fluorescent graphene (FG). FG has a size-, defect-, and wavelength-dependent luminescence emission, which is similar to traditional semiconductor-based quantum dots. Moreover, with excellent chemical stability, fine biocompatibility, low toxicity, up-conversion emission, pH-sensitivity and resistance to photobleaching, FG promises to offer substantial applications in numerous areas: bioimaging, photovoltaics, sensors, etc. Currently, research works have allowed FG to be produced by many approaches ranging from simple oxidation of graphene to cutting carbon sources and organic synthesis from small molecules. In this Feature Article, we summarize the reported fluorescent graphenes, with emphasis on their category, properties, synthesis and applications. Meanwhile, we give a perspective on their subsequent developments and compare the features of FG and other fluorescent carbon-based materials.
