Published: Dec. 14, 2020

Carbon dots (CDs), as a new type of carbon-based nanomaterial, have attracted broad research interest for years, because 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, electron mobility. In this Outlook, we comprehensively summarize the classification CDs based on analysis formation mechanism, micro-/nanostructure property features, describe synthetic methods including strong absorption, photoluminescence, phosphorescence. Furthermore, recent significant advances in applications, (sensor, anticounterfeiting), energy (light-emitting diodes, catalysis, photovoltaics, supercapacitors), promising biomedicine, are systematically highlighted. Finally, envisage key issues to be challenged, future directions, perspectives show full picture CDs-based materials.
