Abstract: Manganese-doped zinc sulfide and copper-doped zinc sulfide were prepared by a chemical precipitation method. The structures and sizes of these clusters were detected by X--ray diffraction.Photoluminescence measurements demonstrate some changes in optical property due to quantum size effect, such as excitation blue shift with size decreasing and faster decay time. The mechanisms of various luminescent centers in zinc sulfide cluster were discussed.

Key words: cluster, dope, quantum size effect, time decay
