摘要

我们展示了用湿化学方法合成的单个ZnO纳米棒的阴极发光测量。观察到强烈的紫外线发射和相对较弱的橙红色发射。能量选择成像技术表明，由于层错缺陷，紫外发射在空间上被调制，而整个纳米棒上的橙红色发光是均匀的。

Cathodoluminescence Characterization of ZnO Nanorods Grown by Wet Chemical Synthesis

We demonstrate cathodoluminescence measurements of individual ZnO nanorods synthesized by wet chemical method. Strong UV emission and relatively weak orange-red emission are observed. Energy-selective imaging technique reveals that the UV emissions are spatially modulated due to the stacking fault defects, while the orange-red luminescence is uniform over the entire nanorods.
