摘要: 700 ℃下,利用热蒸发方法制得四角状和线状氧化锌纳米结构.实验中通过采用不同的反应源以及改变反应时氧气的相对含量来研究这些因素对氧化锌产物的影响.场发射测试展示并比较了这两种不同形貌和尺寸氧化锌的场发射特性.Abstract: At 700℃, ZnO nanostructures with tetrapodlike and wire-like morphologies were synthesized using thermal evaporation method. Different source materials were used and the ambient gas was adjusted to study their influences on ZnO products. Field-emission measurements were applied to compare the field-emission characteristics of the two different morphologies of ZnO nanostructures.
