Abstract: The multi-armed CdS architectures can be synthesized from the reaction of the anhydrous CdCl2 and sulfur powders in ethylenediamine, in which a simple one-step reactant–solvent synchronous (RSS) co-assisted effect was proposed to be responsible to the growth of the multi-armed structures. The as-prepared products were characterized by XRD, XPS and TEM. In addition, their optical properties were also shown by UV–vis and fluorescence spectrum. FT-IR spectrum indicated that the dissociation of ethylenediamine molecule absorbed on the surface of CdS resulted in the formation of intermediate CdS(en) m−n cores and thus provided the condition for the anisotropy growth of CdS. The present technique may give a clue to grow the one-dimensional nano-sized semiconductors by the proper choice of the reactant and the solvent. [Copyright &y& Elsevier]

The novel polygonal flake like Ag8SnS6 crystal, Cu2FeSnS4 flaky, and well-dispersed Cu2CoSnS4 nanoparticles were successfully prepared via a convenient hydrothermal reaction route at relatively low temperature, which was avoiding the use of high temperature treatments or toxic organic solvents. The products were characterized by means of X-ray powder diffraction (XRD), transmission electronic microscopy (TEM), X-ray photoelectronic spectra (XPS) and inductively coupled plasma-atomic emission spectroscopy (ICP-AES). It was found that the reaction temperature played a key role for the formation of the target products. [Copyright &y& Elsevier]

Layered nanocrystallines SnS and β-SnS2 were fabricated through a mild solvothermal route in the temperature range of 180–190°C. Reaction of thiourea with different tin sources (SnCl2·2H2O, SnCl4·5H2O or SnCl4) in organic solvents (benzene or ethanol) has been systematically investigated. By merely adjusting the proportion of the reactants, phase-pure SnS and β-SnS2 could be obtained, respectively. The resulting compounds were examined by XRD and TEM techniques.

Well crystallized PbS rods with the aspect ratios ranging from 2 to 12 were successfully synthesized in ethylenediamine by the so-called SSC route. X-ray powder diffraction, transmission electron microscopy and X-ray photoelectron spectra were used to characterize the as-obtained products. Several factors, such as temperature, synthetic procedure and solvent, which affect the morphologies of PbS nanoparticles were discussed. [ABSTRACT FROM AUTHOR]
