Quantum dots are 15nm-below nanoparticles of Ⅱ-Ⅵ or Ⅲ-Ⅴ group elements. Because of its adjustable color of emission spectra, high yield of fluorescence quantum, stable luminescence and long life, quantum dots are widely used in areas such as biomedical, fluorescence imaging, etc. Preparation method of quantum dot is the organometallic synthesis and aqueous synthesis. Due to the characteristics of the quantum dots, fluorescent quantum dot materials are widely used in the detection of sweat and blood fingerprints. The application of fluorescence quantum dot materials in the imaging of potential fingerprints is one of the trends in development of fingerprint technology, and it has broad prospects for development
