The colloidal, highly crystalline, and size-controlled ZnS nanorods have been prepared through a thermal decomposition of single-source-precursor approach in oleylamine solution. The length and width of nanorods can be controlled simply by varying the molar ratio of zinc 2-mercaptobenzothiazole complex and oleylamine or prolonging the anneal duration. Optical and electrochemical properties of different sizes of ZnS nanorods are discussed and size-dependent optical and electrochemical band gaps are evidently observed, which show a direct correlation between the electronic spectra and electrochemical band gap.
