Abstract

Carbon dots (CDs) present substantial potential in bioimaging, sensing, catalysis, and optoelectronic devices due to their distinctive fluorescent properties, low toxicity, and excellent biocompatibility. Nevertheless, achieving multicolor-tunable fluorescence emission across the entire visible spectrum remains a significant challenge. Recent research has focused on solvothermal synthesis routes to address this, demonstrating the ability to produce a series of multicolor-emitting CDs (p-CDs to r-CDs) by utilizing precursors such as citric acid, benzoic acid, and catechol. This approach enables the creation of multicolor fluorescent inks that exhibit distinct, non-interfering five-color emission under 365 nm ultraviolet (UV) irradiation, indicating promise in anti-counterfeiting and labeling applications. Furthermore, the successful fabrication of red-light-emitting diodes (LEDs) using specific CDs (e.g. r-CDs) demonstrates their viability for advanced lighting and display technologies. These LEDs exhibit an electroluminescence peak at 586 nm and CIE color coordinates of (0.54, 0.43), highlighting their potential for high-performance applications.
