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.
基于荧光石墨烯的材料，被标记为一种荧光碳基纳米材料，近年来引起了越来越多的关注。当石墨烯的尺寸和结构得到适当控制时，石墨烯会产生光致发光，从而产生所谓的荧光石墨烯（FG）。FG 的发光发射具有尺寸、缺陷和波长依赖性，类似于传统的基于半导体的量子点。此外，FG 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、对 pH 值的敏感性和抗光漂白性，有望在许多领域得到广泛应用：生物成像、光伏、传感器等。目前，研究工作已经允许通过从简单的氧化石墨烯到切割碳源和从小分子进行有机合成的多种方法来制备 FG。在这篇专题文章中，我们总结了报道的荧光石墨烯，重点介绍了它们的类别、性质、合成和应用。同时，我们对它们的后续发展进行了展望，并比较了 FG 和其他荧光碳基材料的特点。
