Morphology Controlled Synthesis of ZnS(en)_0.5Nanostructures via a Novel Mixed-Solvent Solvothermal Process

Abstract:

By using a mixed-solvent solvothermal process, we report a simple and general approach for the morphology controlled synthesis of well-defined ZnS(en)0.5(en=ethylenediamine) rectangular nanosheets. The structure, and morphology of the as-synthesized products were investigated by using XRD, SEM, and TEM. By continuously adjusting the ratio between ethylenediamine and ethylene glycol, cuboid nanocrystals, nanosheets, short nanorods and nanoparticles have been successfully achieved. This conclusive evidence shows that the ratio of solvents played a key role in the morphology-controlled synthesis process. The UV-vis absorption spectrum shows that the morphology evolution provides us an opportunity to structurally modulate physical property, i.e. the energy gap. This simple approach of modulating the physical property promises future application in applied optics, optoelectronic and luminescent instruments.
