摘要

Nanocrystalline Bi_2Te_3 was synthesised via a microwave-assisted polyol method. Elemental Te and bismuth nitrate were used as Te and Bi source, respectively. The product was characterized by powder X-ray diffraction (XRD), selected area electron diffraction (SAED), X-ray photoelectron spectra (XPS) and transmission electron micrographs (TEM) measurements. The as-prepared Bi_2Te_3 was found to be the mixture of nanorods (20-50 nm in width and 200-400 nm in length) and hexagon nanoflakes (with edge length ranging from 90 to 150 nm). The possible mechanisms were also discussed.
