    Properties of Carbon Dots Synthesized Solvothermally from Citric Acid and Urea

    We propose a simple one-stage method to prepare carbon dots using citric acid as a carbon source and urea as a nitrogen source. It is shown that luminescence spectra of carbon dots depend on the excitation wav...
