Abstract

Carbon quantum dots (CQDs) were synthesized from Trachyspermum ammi seeds through a green hydrothermal method. The CQDs exhibited strong fluorescence, high stability, and abundant surface functionalities. They showed dual functionality by enabling selective detection of toxic metal ions and temperature-dependent photoluminescence for nanothermometry. This eco-friendly approach provides a sustainable route to multifunctional nanomaterials with promising applications in environmental monitoring and analytical sensing.
