Hydrothermal method for synthesis of HgTe nanorods in presence of a novel precursor

چکیده مقاله

In the present paper, we successfully prepared HgTe nanostructures via hydrothermal route by employing Hg(salen) (H2salen = N,N´-bis-salicylidene-1,2-ethylendiamine) as a mercury source, TeCl4 and N2H4.H2O as the starting reactants at 180 °C for 12 h. Some factors which affecting the morphologies of the HgTe nanostructures, such as the reaction temperature and time, capping agent, sorts of reductants and alkaline, were systematically investigated. X-ray diffraction analysis (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) images indicate phase, particle size and morphology of the products. Chemical composition and purity of the products were characterized by X-ray energy dispersive spectroscopy (EDS). UV-visible was used to study the optical properties of HgTe samples.
