摘要: Quantum dots can be overcome traditional organic fluorescent dye deficiencies，such as the narrow of absorption spectra，the tailing of emission spectrum. Therefore，quantum dots can be used as a new type of fluorescent probe in resonance energy transfer technology，instead of the traditional organic fluorescent dye. In recent years, the study of quantum dots used in resonance energy transfer technology research become more widely, this paper review the application of quantum dot used in fluorescence resonance energy transfer in recent years.
