采用牺牲Zn基片上ZnO 纳米柱模板技术，以三乙醇胺(TEA)为溶剂，以 HSe-离子为硒源，在150℃恒温8 h 制备了 ZnSe 亚微米管。采用 FE-SEM、EDS、XRD、TEM 及SAED手段对样品的形貌、结构及成分进行了表征。结果表明，多晶管状ZnSe的直径为150 nm左右，且具有封口、规则开口、不规则开口以及呈半管状，管壁由直径约30~40 nm 左右的颗粒组成。据此形貌特征，依负离子多面体生长基元模型，分析了ZnSe亚微米管的形成机制。
Polycrystalline ZnSe submicro-tubes on the zinc substrate were fabricated via the sacrificial zinc oxide temple route in HSe- ion solution of TEA at 150 ℃ for 8 h.The structures and morphologies of as-synthesized samples were characterized by FE-SEM,EDS,XRD,TEM and SAED.The average diameter of ZnSe tubes was 100-150 nm with the closed ends,the regular open ends,irregular open ends,and even the semi-tube ends. The wall of submicro-tubes consists of the particles with the diameter of 30-40 nm.According to the growth unit model of anion coordination polyhedron,the formation mechanism of ZnSe submicro-tubes was suggested.
