Disclosed are a preparation method of a heteroatom doped multifunctional carbon quantum dot, and application of the heteroatom doped multifunctional carbon quantum dot in fields of biomedicine, catalysts, and photoelectric devices. The heteroatom carbon quantum dot is prepared by using a conjugated polymer as a predecessor which is processed in a high temperature carbonization process. These carbon quantum dots comprise one or more of heteroatoms, such as N, S, Si, Se, P, As, Ge, Gd, B, Sub-box, and Te, whose absorption spectrum ranges from 300 to 850 nm, and the fluorescence emission wavelength 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 photodynamic medicine for heating cancer and sterilization, photocatalytic degradation of organic pollutants, photocatalytic splitting decomposition of water for preparing hydrogen, organic polymer solar cell and quantum dot sensitization solar cell. |
