Graphene quantum dot (GQD) is one of the youngest superstars of the carbon family. Since its emergence in 2008, GQD has attracted a great deal of attention due to its unique optoelectrical properties. Non-zero bandgap, the ability to accommodate functional groups and dopants, excellent dispersibility, highly tunable properties, and biocompatibility are among the most important characteristics of GQDs. To date, GQDs have displayed significant momentum in numerous fields such as energy devices, catalysis, sensing, photodynamic and photothermal therapy, drug delivery, and bioimaging. As this field is rapidly evolving, there is a strong need to identify the emerging challenges of GQDs in recent advances, mainly because some novel applications and numerous innovations on the ease of synthesis of GQDs are not systematically reviewed in earlier studies. This feature article provides a comparative and balanced discussion of recent advances in synthesis, properties, and applications of GQDs. Besides, current challenges and future prospects of these emerging carbon-based nanomaterials are also highlighted. The outlook provided in this review points out that the future of GQD research is boundless, particularly if upcoming studies focus on the ease of purification and eco-friendly synthesis along with improving the photoluminescence quantum yield and production yield of GQDs.

石墨烯量子点的合成、应用与展望：综合综述
石墨烯量子点（GQD）是碳家族中最年轻的超级巨星之一。自2008年问世以来，GQD因其独特的光电特性而备受关注。非零带隙、容纳官能团和掺杂剂的能力、优异的分散性、高度可调的特性和生物相容性是 GQD 最重要的特性之一。迄今为止，GQDs 在能源设备、催化、传感、光动力和光热疗法、药物输送和生物成像等众多领域都表现出显着的发展势头。由于该领域正在迅速发展，因此迫切需要在最近的进展中识别 GQD 的新挑战，这主要是因为早期研究中没有系统地回顾 GQD 易于合成的一些新应用和众多创新。这篇专题文章对 GQD 的合成、性质和应用方面的最新进展进行了比较和平衡的讨论。此外，还强调了这些新兴的碳基纳米材料的当前挑战和未来前景。本综述中提供的展望指出，GQD 研究的未来是无限的，特别是如果即将进行的研究集中在易于纯化和环保合成，同时提高 GQD 的光致发光量子产率和生产产率。
