A novel synthesis method of ZnS chain-like nanospheres by supported liquid membrane system has been investigated. The system, with o-phenanthroline as a mobile carrier, can selectively transport zinc ions to the other side of the membrane. Nucleation process was under the control of SLM template effect by directionally combining anion, local super saturation solution and the interfacial microenvironment. XRD and TEM data indicated that the crystal has cubic structure of blende with cell constant of α＝0.5390 nm in the range of 250～300 nm. In addition, the morphological formation mechanism and luminescence properties of ZnS have been discussed.
