Abstract A series of CdSe QDs are synthesized using four kinds of ligands including dodecylamine, tetradecylamine, 1-hexadecanamine and octadecylamine by organic metal preparation method. The XRD patterns revealed that all the CdSe QDs with different amine ligands belong to cubic phase. The monodisperse CdSe QDs are obtained and their average size increases with the Carbon chain length of amine ligands. The absorption peaks of CdSe QDs capping with different amines shift from 526 to 557 nm. The results indicated that the luminescent properties and size of CdSe QDs can be modulated by amine ligand in the process of synthesis.
