摘要：
The present invention discloses a method for preparing heteroatom doped carbon quantum dot, and application thereof in fields of biomedicine, catalysts, photoelectric devices, etc. The various kinds of heteroatom doped carbon quantum dots are obtained by using a conjugated polymer as a precursor and through a process of high temperature carbonization. These carbon quantum dots contain one or more heteroatoms selected from the group consisting of N, S, Si, Se, P, As, Ge, Gd, B, Sb and Te, the absorption spectrum of which ranges from 300 to 850 nm, and the fluorescence emission wavelength of which is within a range of 350 to 1000 nm. The carbon quantum dot has a broad application prospect in serving as a new type photosensitizer, preparing drugs for photodynamic therapy of cancer and sterilization, photocatalytic degradation of organic pollutants, photocatalytic water-splitting for hydrogen generation, organic polymer solar cell and quantum dot-sensitized solar cell.
