中文摘要	facile synthesis of straight and branched cdte nanowires using cdo as precursor
英文摘要	high-quality colloidal cdte nanowires (nws) containing both straight and branched ones were controllably prepared via a solution-based approach, using a low melting bi nanoparticles as catalysts, cdo and tributylphosphine telluride (tbp-te) as precursors, and a tri-n-octylphosphine oxide/trin-octylphosphine (topo/top) mixture as solvent. the resulting straight cdte nws have typical diameters below 20 nm accompanying with lengths exceeding 10 mu m. in the case of branched cdte nws, tripod, v-shaped and y-shaped morphologies are obtained by decreasing the apparent cd/te molar ratio. it is found that, as the surface capping ligands, di-n-octylphosphinic acid (dopa) is superior to decylphosphonic acid (dpa) in the reproducible growth of high-quality cdte nws. since highly toxic dimethylcadmium, a cadmium precursor widely used in literatures, is replaced by cdo and the amount of the topo/top solvent mixture is significantly reduced, a relative safe and economical synthetic approach of high-quality colloidal cdte nws with controllable morphology is thus presented.
