Preparation of Bi2Te3 Nano-powders via an Aqueous Chemical Method

摘要：

　　Using NaBH4 as reductant,Bi2Te3 nano-powders with different morphology such as nano-rod and nano-sphere were synthesized from BiCl3 and Te through an aqueous chemical method at temperatures below 100℃.The nano-rods were 100~200nm in diameter and 10~2μm in length,the diameter of the nano-spheres is between 100 and 500nm.The phase purity of the powders was analyzed by XRD,micro morphology and chemical compositions were characterized by SEM and EPMA.The reaction mechanism was discussed.
