辅助水热法制备不同形貌的柱状ZnO微晶(英文)

Different Morphology Rod-like ZnO Microcrystals Grown by Ethanol Assisted Hydrothermal Method

本文采用乙醇辅助水热法制备得到了柱状ZnO微晶。得到的微晶形貌多样,有单脚、三脚、四脚、五脚、六脚以及多脚状,并以“骨架+支架”模型进行解释。X射线衍射分析结果表明产物为纯的六方相纤锌矿结构,扫描电子显微镜(SEM)观察表明产物具有单晶属性。本文还研究了ZnO的室温光谱性能。

Rod-like ZnO microcrystals have been synthesized via ethanol assisted hydrothermal method. Straight rod-, tripod-, tetrapod-, quinpod-, senapod-, and muhipod-like ZnO were discovered in the obtained ZnO microcrystals, which can be explained by ＇ Backbone and Arms＇ model. X-ray diffraction （ XRD ） results show that the microrods are of hexagonal wurtzite structure, and scanning electron microscopy （ SEM ） show that ZnO microrods are single crystal in nature. Photoluminescence （PL） spectrum of ZnO micorods was also investigated at room temperature.
