摘要
利用水-乙醇混合溶液为溶剂的溶剂热的方法,合成了不同形貌的ZnO纳米-亚微米结构.通过X-射线粉末衍射,扫描电镜,紫外可见光谱等测试手段对样品的结构和光学性能进行了表征.结果表明,溶液的碱性对产物形貌有很大影响.随着氨水加入量的增多,产物形貌从纺锤型逐渐发展为一维棒状直至花型结构.我们可以通过简单调节溶液的酸碱性来实现对产物氧化锌形貌的控制.
Here we report growth of different morphologies of ZnO by a solvothennal method, in which the mixture of H2O-C2H5OH was used as the solvent. The structures and optical properties of the samples were studied by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and Ultra-Violet Visible Spectum （UV）. It was found that the basicity of the solution had great influence to the products shape. With the increase amount of ammonia, the morphologies changes from spindle-like to 1-D nanorods until to nanoflowers. It indicates that we can control the morphology of ZnO nanostructures by simply adjusting the basicity.
