快速加热化学气相沉积法制备氧化锌四足纳米结构
Synthesis of ZnO nanotetrapods through a rapid heating chemical vapor deposition (CVD) method
本文利用快速加热的化学气相沉积法，在无需真空和载气的情况下，在750°C ~ 790°C反应温度范围内大量地合成了均匀的四足氧化锌纳米结构。X射线衍射图谱表明所合成的纳米结构为六方纤锌矿结构，透射电子显微镜表征结果显示每条纳米足的生长方向沿[0001]晶体学方向。光致发光光谱表明：随着生长温度的降低，四足氧化锌纳米结构的结晶性能变好。而且，后续退火可以提高其结晶性能，并且随着退火温度的提高其结晶性变好。
In this paper, large scale homogeneous ZnO nanotetrapods (NTs) were synthesized by a simple rapid heating CVD method without vacuum-pumping and carrying gas at 750°C ~ 790°C. XRD pattern reveals the as-synthesized ZnO NTs are hexagonal wurtzite structure. TEM images indicate that the growth direction of their arms is along [0001] crystallographic direction. Raman and photoluminescence (PL) spectra indicate that with decreasing growth temperature, the crystallinity of ZnO NTs became better in above temperature range. Furthermore, their crystallinity was enhanced by post annealing and increased with annealing temperature from 400°C to 900°C.
