Abstract: The present invention relates to nitrogen-doped carbon dots, which allow simple eco-friendly determination of water content in an organic solvent, pH of a solution, polarity of a solution, or the like, by using the fluorescence properties thereof, and a method for preparing the same. Since the nitrogen-doped carbon dots show a solvent-dependent color development phenomenon in which the maximum wavelength range of fluorescence spectrum varies depending on the polarity of a solvent, it is possible to determine the polarity (relative polarity) of a solvent by measuring the maximum wavelength of fluorescence spectrum of the nitrogen-doped carbon dots dispersed in a solvent. Since the nitrogen-doped carbon dots show a red shift of the maximum wavelength of fluorescence spectrum and a decrease in fluorescence intensity according to an increase in water content in an organic solvent, it is possible to determine water content in an organic solvent by measuring a fluorescence color or intensity of a solution (the organic solvent contains water). Since the nitrogen-doped carbon dots show a linear increase in fluorescence intensity depending on an increase in pH in a solution, it is possible to determined the pH of a solution by measuring the fluorescence intensity of the nitrogen-doped carbon dots dispersed in a solution.
