摘要：
Fish scale collagen peptides were used as a precursor to prepare carbon dots using conventional hydrothermal (CDs-HT) and microwave (CDs-MW) methods. The optical properties of CDs prepared using the two methods were compared and the influence of the heating method on the structure of CDs was analyzed. Both CDs emitted blue fluorescence and exhibited an excitation-dependent emission character. The rapid and uniform heating during the microwave method is more conducive to the self-doping of nitrogen. Although CDs-HT have a lower doping amount of nitrogen, the relative content of pyrrolic N is hi...
