Carbon dots (CDs), as a new type of carbon-based nanomaterial, have attracted broad research interest for years, because of their diverse physicochemical properties and favorable attributes like good biocompatibility, unique optical properties, low cost, ecofriendliness, abundant functional groups (e.g., amino, hydroxyl, carboxyl), high stability, and electron mobility. In this Outlook, we comprehensively summarize the classification of CDs based on the analysis of their formation mechanism, micro-/nanostructure and property features, and describe their synthetic methods and optical properties including strong absorption, photoluminescence, and phosphorescence. Furthermore, the recent significant advances in diverse applications, including optical (sensor, anticounterfeiting), energy (light-emitting diodes, catalysis, photovoltaics, supercapacitors), and promising biomedicine, are systematically highlighted. Finally, we envisage the key issues to be challenged, future research directions, and perspectives to show a full picture of CDs-based materials.

碳点：一种应用广泛的新型碳基纳米材料

碳点（CDs）作为一种新型碳基纳米材料，由于其多样化的理化性质以及良好的生物相容性、独特的光学性能、低成本、环境友好、丰富的官能团等优点，多年来引起了广泛的研究兴趣。例如氨基、羟基、羧基），稳定性高，电子迁移率高。在本展望中，我们在分析碳点的形成机制、微纳结构和性能特征的基础上，全面总结了碳点的分类，并描述了其合成方法和强吸收、光致发光、磷光等光学性质。此外，系统地强调了最近在光学（传感器、防伪）、能源（发光二极管、催化、光伏、超级电容器）和有前景的生物医学等不同应用领域取得的重大进展。最后，我们展望了需要挑战的关键问题、未来的研究方向和展望，以展示基于CD的材料的全貌。
