Abstract:

CQDs have the characteristics of easy preparation, low toxicity, high chemical inertia, stable fluorescence properties and so on. CQDs and other carbon nanomaterials (such as fullerene, carbon nanotubes and graphene) have attracted the attention of researchers. The synthesis, properties, modification and application of CQDs are discussed in this paper, especially on the Up Conversion Photoluminescence that long wavelength excitation can emit short wavelength. Some implications for the synthesis, modification and application of CQDs based on up conversion photoluminescence are discussed in this paper too.

Key words: up conversion luminescence, carbon quantum dots, synthesis, modification
