微波加热制备空心和锯齿形貌Bi_2Te_3晶体(英文)

Well-crystallized Bi₂Te₃ hollow spheres and nanosaws were prepared by microwave heating. Both the ionic liquid and the microwave heating play important role in the formation of the above nanostructures. Hollow spheres can not be obtained only by electronic stove heating, while the addition of ionic liquid leads to fast preparation of nanosaws structure under microwave heating conditions. The similar experimental results have been observed in the preparation of Bi₂S₃, Sb₂S₃ and Bi₂Se₃ nanostructures.
