Scholarcy highlights

  • Carbon dots with a high quantum yield have been synthesized by a facile and green one-pot approach under microwaves with silkworm chrysalis as the natural carbon source, without using any other chemicals/reagents
  • The morphology and optical properties of the resultant CDs are characterized by TEM, XRD, FT-IR, XPS, UV-vis and photoluminescence
  • The SC-CDs have an average size of 19 nm, and contain C, O and N with relative contents of ca. 71.32%, 22.96% and 5.72%, respectively
  • It is further demonstrated that the SC-CDs exhibit a low cytotoxicity at a higher concentration of 15 mg mL−1 and they are able to display bright blue, green and red colors under an inverted fluorescence microscope during cell imaging experiments, showing their vast potential in bioimaging
