Phase Evolution and Morphology Control of ZnS in a Solvothermal System with a Single Precursor

A series of ZnS nanostructures with controllable crystal phase and morphology were synthesized by a solvothermal method using Zn(NCS)2(C5H5N)2 as a precursor. Nanospheres, microflowers, and microspheres assembled with hexagonal or cubic nanocrystals were obtained in different solvents. Phase evoluti...

Description
Summary:A series of ZnS nanostructures with controllable crystal phase and morphology were synthesized by a solvothermal method using Zn(NCS)2(C5H5N)2 as a precursor. Nanospheres, microflowers, and microspheres assembled with hexagonal or cubic nanocrystals were obtained in different solvents. Phase evolution of ZnS in polyols was also discussed. Hexagonal ZnS is stable in polyols with neighboring hydroxyl, whereas cubic ZnS is stable in polyols without neighboring hydroxyl. The ligation of hydroxyl groups with Zn atoms on the surface of ZnS is responsible for the phase evolution of ZnS in polyols.
