Synthesis of uniform CoTe and NiTe semiconductor nanocluster wires through a novel coreduction method.
A novel coreduction method was developed to synthesize uniform one-dimensional CoTe and NiTe nanocluster wires. In the synthesis, soluble Na(2)TeO(3) was used to supply a highly reactive Te source and N(2)H(4).H(2)O was used both as reducing agent and as complexing agent. The as-prepared samples were characterized by XRD, TEM, and HRTEM. The probable formation mechanism of the nanowires is discussed.

Synthesis and characterization of an open framework ballium selenide: Ga4Se7(en)2 x (enH)2.
An open framework gallium selenide, Ga(4)Se(7)(en)(2).(enH)(2), has been prepared by the direct reaction of gallium (Ga) and selenium (Se) in ethylenediamine (en), in which both covalent and hydrogen bonds have been employed to combine the inorganic structures and organic spacers to build layers with micropores. Its structure has been determined by X-ray diffraction. Its thermal and optical properties have been characterized by TGA and UV-vis, Raman, and IR spectroscopies, respectively.

Selective synthesis and characterization of CdSe nanorods and fractal nanocrystals.
CdSe nanorods and dendritic fractals were synthesized through a novel controllable solution-phase hydrothermal method. Soluble selenite was employed to provide a highly reactive Se source in the synthesis. Both morphologies and phases of the CdSe products could be successfully controlled by choosing appropriate complexing agents to adjust the dynamics of the reaction process. Reaction temperature and Cd/Se ratio in raw materials were also important parameters influencing the morphologies and phases of the products. The phase structures, morphologies, and optical properties of the CdSe products were investigated by XRD, TEM, HRTEM, and UV-vis and photoluminescence spectroscopies. The formation mechanisms of the nanorods and fractals were investigated and discussed on the basis of the experimental results.
