摘要
本文利用化学气相沉积法制备ZnO纳米材料,通过只改变管式炉内的反应温度制备了不同维度的纤锌矿结构的ZnO纳米材料,包括零维的ZnO纳米球壳,一维的ZnO纳米线和二维的ZnO纳米片。利用多种透射电子显微学手段对不同维度的ZnO纳米结构进行了深入表征,并对得到的ZnO纳米材料进行PL和XPS测试,最后基于纳米材料的尺寸效应与“V-S”生长机制成功解释ZnO纳米材料的生长机理。
Based on chemical vapor deposition,various dimensional ZnO nanomaterials with wurtzite structure have been synthesized by only changing the heating temperature,including zero-dimensional nanospheres,one-dimensional nanowires and two-dimensional nanosheets.The ZnO nanostructures with different dimensions were characterized by various transmission electron microscopy methods and optical method.Additionally,the obtained ZnO nanomaterials were tested by PL and XPS.Finally,the growth mechanism of ZnOnanomaterials was successfully explained based on the size effect of nanomaterials and“V-S”growth mechanism.
