Summary
These days, carbon quantum dots (CDs) as semiconductor synthesized nanoparticles have turn into a pretty topic for many functions because of their exceptional options. Within the present research, the extremely fluorescent (FL) CDs with nice traits had been synthesized by means of a novel one-step microwave irradiation by citric acid monohydrate and urea as carbon precursors. The as-prepared CDs had been quasi-spherical form with a mean diameter of 4.5 nm and emitted brilliant blue FL below ultraviolet mild irradiation (UV). Moreover, the synthesized CDs possessed totally different properties equivalent to numerous purposeful teams, good sensitivity and selectivity, excessive water-solubility, low toxicity, and vital stability in varied environmental situations. The outcomes indicated that the as-prepared CDs could be utilized as a fluorescent probe for detection of various concentrations of tartrazine from 5 to 100 µM in meals samples. As well as, the findings revealed that the nice linear relationship was obtained between the FL depth of CDs and totally different concentrations of tartrazine over the vary of 5 to 100 µM with the detection restrict of two.58 µM.
