Abstract:Selective and sensitive detection of Cyanide (CN−) is critical essential due to it is one of the most lethal chemicals and threat to human health. In this study, nitrogen‐doped carbon quantum dots (N‐CQDs) were synthesized by one‐step hydrothermal method using 4‐aminosalicylic acid and tartaric acid as raw materials. The prepared N‐CQDs were spherical particles with good water solubility and uniform particle size distribution, the optimal excitation and emission wavelengths of N‐CQDs were 495 nm and 514 nm, re… Show more
