General description

As a new class of fluorescent carbon nanomaterials, carbon quantum dots (CQDs) have drawn a lot of attention due to their attractive properties such as high stability, good conductivity, biocompatibility, low toxicity, environmental friendliness, dispersibility in water and low photobleaching.
Our CQDs possess the strong and tunable fluorescence emission properties that are controllable by excitation wavelength and enable their applications in imaging, biomedicine, optronics, catalysis, and sensing.

Application

  • Bioimaging
  • Photocatalysis
  • LED
  • Energy conversion
  • Sensing
