Simple and Green Synthesis of Carbon Dots from the Fruit of the Pyracantha Plant

Carbon Dots is the new class of fluorescent carbon nanoparticles with a particle size of less than ۱۰ nm that have many applications in various fields including Bioimaging, Bioassays, and disease diagnosis. These particles have excellent biocompatibility, unique optical properties, high stability, low toxicity, and good solubility in water. In this study, Pyrolysis and Hydrothermal methods are used to make these Carbon Dots, which are cost-effective and easy methods. In the hydrothermal method, the precursor of the Pyracantha fruit, was prepared and placed in a ۵۰ ml stainless steel autoclave then distilled water was added, afterward placed in the oven. By optimizing the plant precursor ratio, temperature, and reaction time ،carbon dots with high fluorescence property was obtained. In the Pyrolysis method،the precursor was subjected to high and direct oven temperature and carbon dots with optimal fluorescence was obtained. Subsequently, by comparing the fluorescence intensity of Carbon Dots obtained from both methods, the hydrothermal method was selected as a more appropriate method due to its higher fluorescence emission. In general, these prepared carbon dots have promising potential and many applications in nanotechnology.
