Cage-like nano-tetrapod ZnO is a novel structure, which was successfully synthesized by combustion oxidation at 850 degrees C. No catalyst or carrier gases were used. Thorough SEM and TEM analyses revealed that the linking legs of the tetrapod ZnO can have or not interface. The formation or not of an interface is discussed and it was attributed to different growth process of the cage-like ZnO nano-tetrapod. Enhanced UV emission peak at the wavelength of 375 nm, featuring high intensity and narrow width, indicates a highly crystalline structure. A green emission, recorded at 502 nm, was related to the defects of the surface of the branching configuration as well as to the ZnO nuclei of the cage-like nano-tetrapod ZnO.
笼状纳米四足氧化锌是一种新型结构,它在850摄氏度下通过燃烧氧化成功合成。未使用催化剂或载气。全面的扫描电子显微镜(SEM)和透射电子显微镜(TEM)分析表明,四足氧化锌的连接腿可能有或没有界面。讨论了界面的形成与否,并将其归因于笼状氧化锌纳米四足体的不同生长过程。在375纳米波长处增强的紫外发射峰,具有高强度和窄宽度,表明其具有高度结晶的结构。在502纳米处记录到的绿色发射与分支结构表面的缺陷以及笼状纳米四足氧化锌的氧化锌核有关。
