Fluorescent Carbon Dots Data for Nitrite Concentration Detection

Experimental data from a study on a fluorescent carbon dots probe for nitrite detection, fabricated via a hydrothermal method. The dataset includes measurements from transmission electron microscopy, X-ray diffraction, UV-Vis absorption, and fluorescence spectrophotometry. The relationship between fluorescence intensity and nitrite concentration is modeled by a Stern-Volmer equation with a linearity of R²=0.99.

Use Cases

• Analyze the relationship between relative fluorescence intensity and nitrite concentration using the Stern-Volmer equation parameters.
• Study the quenching effect on carbon dots by correlating fluorescence data with nitrite concentration and pH levels.
• Model the interaction between electron-donating functional groups and nitrous acid based on fluorescence spectrophotometer readings.
• Validate the linear detection range of the carbon dots-based probe using the provided calibration data.

Strengths

• Data supports a Stern-Volmer calibration model with a reported linearity of R²=0.99.
• Includes characterization from multiple analytical techniques: transmission electron microscope, X-ray diffractometer, UV-Vis absorption spectrometer, and fluorescence spectrophotometer.
• Probe performance is evaluated under varying pH conditions, providing context for the quenching mechanism.

Limitations

• The specific sample size, number of experimental replicates, and raw data rows are not provided.
• Dataset scope is limited to the specific carbon dots probe and nitrite interaction described, with no comparative data for other materials.
• Data is from a single study published in 2020, with no indication of updates or expanded validation.
