Copper doped ZnS (ZnS:Cu) nanocrystals were synthesized by using MPA (3-mercaptopropionic acid) as the stabilizer under microwave irradiation. XRD, UV-Vis and photoluminescence measurements were employed to study the crystal structure and optical properties of the ZnS:Cu nanocrystals respectively. It was found that by varying the microwave irradiation conditions, the size of nanocrystal could be changed and the luminescence could be, tuned continuously within the range from 460 to 572 nm. The photoluminescence properties of ZnS:Cu were clarified by considering the quantum size effect.
