采用低温气相传输方法,在不同的氧分压、生长时间、生长温度和衬底上有无Ni等生长条件下合成一系列一维ZnO纳米结构。结果显示,衬底上沉积的Ni会导致产物的结构多样化,温度的不同会影响纳米线的排列分布,并且这些生长条件对产物的尺寸都有影响。因此改变生长条件能改变ZnO的形貌,可能在一定程度上实现ZnO的可控生长。
One-dimensional ZnO nanostructures are fabricated by low-temperature vapor phase transport method at various partial pressure of oxygen, growth time, growth temperatures as well as substrates with or without Ni. The results reveal that the size of ZnO nanostructures can he all changed by changing any above-mentioned growth condition. In addition, the comb-like structure can be synthesized on Si substrate with Ni besides ZnO nanowires, and ZnO nanowire arrays can be obtained at high temperature compared with that at low temperature. So the ZnO nanostructures can be dyrealized controllable growth by controlling growth conditions.
