Hydrothermal preparation and characterization of Cd0.9Mn0.1S nanorods

Cd0.9Mn0.1S semiconductor nanorods were successfully prepared by the hydrothermal reaction of CdCl2·2.5H2O and MnCl2·5H2O with (NH4)2S in aqueous solution. Atomic absorption spectrometry (AAS) and energy dispersive spectroscopy (EDS) were used to determine the Mn contents of these complex nanorods. The samples were characterized by scanning electron microscopy (SEM-EDS), X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–vis absorption spectra, photoluminescence (PL) and compared with the undoped CdS nanorods. The results showed that nanostructured multiplex compounds with high aspect ratio were obtained via hydrothermal method. The products showed almost totally rod-like morphology with approximately identical diameter about 20 nm and the maximal length up to 200 nm.
