笼状纳米氧化锌是一种新型结构，采用燃烧氧化法在850 ℃下成功合成。不使用催化剂或载气。SEM和TEM分析表明，四脚ZnO的连接腿可以有或没有界面。讨论了界面的形成和未形成的原因，认为是由于笼状氧化锌纳米四足体的生长过程不同。在375 nm波长处的增强的UV发射峰具有高强度和窄宽度的特征，表明高度结晶的结构。一个绿色发射，记录在502 nm处，有关的分支结构的表面缺陷，以及对笼状纳米四足ZnO的ZnO核。
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.
