Synthesis and characterization of Se nanowires

This paper introduces a green environment-friendly approach used for the preparation of t-Se nanowires with Alkaline conditions, redox reaction has been used for the synthesis of gray black t-Se nanowires in redox system. Sucrose, dextran has been used for agent-oriented and software templates, preparation of a large number of selenium nanowires has been prepared with uniform size, different morphologies. The morphologies and structure were characterized using XRD, SEM. It was shown that two different kinds of sugar has different effects on the growth of selenium nanowires, Se nanowires is typically about 6 μm long, 80-300 nm in diameter in sucrose conditions. But Se nanowires is typically about 0.5 cm long, over 500 nm in diameter in dextran conditions;it was also shown that the Se nanowires with high crystallinity were trigonal selenium and grown along [001] direction.
