| Abstract: | Bundle‐like cadmium sulfide (CdS) nanostructures assembled by high‐quality nanorods have been successfully synthesized on a large scale via a facile solvothermal route in a mixed solvent of ethylenediamine and dodecanethiol. The typical lengths of bundle‐like CdS nanostructures are several tens of micrometers, and the diameters and lengths of CdS nanorods are about 50–70 nm and several micrometers, respectively. The influence of the concentration of dodecanethiol on the morphologies of CdS nanostructures has been investigated carefully. Photoluminescence spectra (PL) of CdS nanostructures reveal that the bundle‐like CdS nanostructures exhibited two fluorescence emission peaks centered at 495nm (2.51 eV) and 522 nm (2.38 eV) as the excitation wavelength is 405 nm.
