摘要：以碲化铋(Bi2Te3)为研究对象，综述气相合成法、模板电沉积法、溶剂热法、气相传输法、电置换法以及新型的低温双溶剂溶胶-凝胶法等6种典型的制备Bi2Te3纳米材料的方法，总结Bi2Te3纳米材料在光电探测器、太阳能电池和热电发生器等方面的应用;提出低成本、高效、可控的制备Bi2Te3纳米材料是其得到进一步广泛应用的重要前提，认为在之后的研究中，应着重考虑采用降低材料维度或掺杂的方式构建具有高热电优值(ZT)的热电器件，采用异质结的方法构建高光响应性能的光电器件。

Abstract：Taking bismuth telluride( Bi2Te3) as the research object,6 typical preparation methods of Bi2Te3 nanomaterials,such as gas-phase synthesis,template electrodeposition,solvothermal,gas phase transfer,electrical displacement and new low-temperature double solvent sol-gel method,were reviewed. The applications of Bi2Te3 nanomaterials in photodetectors,solar cells and thermoelectric generators were summarized. It is proposed that low-cost,efficient and controllable preparation of Bi2Te3 nanomaterials is an important prerequisite for its further application. In the future research,we should focus on reducing the material dimension or doping to build thermoelectric devices with high figure of merit and heterojunction to build optoelectronic devices with high photoresponse performance.
