Effects of reaction conditions on the structural, morphological and optical properties of solvothermal synthesized ZnS nanostructures

Structural and morphological controlled ZnS nanostructures were synthesized with solvothermal method by using the mixed solvent of ethylenediamine (En) and deionized water. ZnS nanowires were synthesized successfully. The mechanism of the morphological evolution of ZnS nanostructures was concluded by studying the influences of different synthetical conditions on the properties of ZnS nanowires, which included the volume ratios of En and deionized water, the mole ratios of two precursors, different zinc precursors, reaction temperatures and times. The optical properties of ZnS nanostructures were also examined by photoluminescence and absorption spectra.
