Abstract
Using hydrazine hydrate (N2H4·H2O) as the solvent, bundles of wurtzite ZnS nanowires with diameters of 10−25 nm and lengths about 5−8 μm have been synthesized in high yield via a solvothermal route. The formation process of ZnS nanowire bundles was studied, and it was found that the initially formed N2H4 intercalated zinc sulfide served as the precursor to ZnS. Based on the experimental results, the formation mechanism was discussed. The effect of solvent on the determination and evolution of the morphologies of the resulting nanocrystals was investigated. The optical properties of the as-synthesized wurtzite ZnS nanowire bundles were characterized by UV−vis absorption and PL spectrum.
