Article Synopsis
- Carbon dots are a new type of zero-dimensional nanomaterial with potential applications, but their aggregation can reduce fluorescence and limit their use.
- A newly developed sulfur-doped carbon dot (S-CD) shows different fluorescence properties depending on its state, emitting blue fluorescence in ethanol and orange in solid form due to aggregation-induced emission (AIE).
- This study highlights the unique features of S-CDs, such as S-S bonds and reduced rotation of aromatic rings in solid state, and suggests their practical use in areas like fingerprint identification and anti-counterfeiting.

Carbon dots (CDs) as luminescent zero-dimensional carbon nanomaterials have good aqueous dissolution, photostability, high quantum yield, and tunability of emission color. It has great application potential in many fields, including bioimaging, labeling of biological species, drug delivery, and sensing in biomedical. However, controlling the fluorescence emission of carbon dots remains a formidable challenge.
