Abstract: The importance of quantum dots(QDs) in fingerprints development, the preparation and optical properties of quantum dots are summarized in the paper. Especially recent progress of chemical synthesis, modification and application in fingerprint development of Ⅱ~Ⅵ quantum dots such as CdS series, CdTe series, CdSe series, ZnSe series, Ⅲ~Ⅴ quantum dots such as InP are discussed. Finally, the recent research of Ⅳ quantum dots(C and Si QDs) and the prospect for potential application in crime scence are also discussed.

Key words: quantum dots, fluorescence, fingerprint, development
