Abstract: The quantum dots（QDs）have the feature that the emission spectrum can be regulated with particle size，the emission spectrum scope can be regulated with the element composition or the particle size of QDs，the luminous efficiency and the color purity are high. In recent years，QDs are widely applied in displaying and luminous domain. The surface ligands can influence the luminous efficiency of QDs，reviews the recent research status of QDs surface ligands at home and abroad，and the effects of different ligands on the nucleation， growth， shape， fluorescence properties and stability of QDs.

Key words: quantum dots（QDs）, ligand, shape, stability
