Hierarchical SnO(2) microspheres consisting of nanosheets on the fluorine-doped tin oxide (FTO) glass substrates are successfully prepared via a facile hydrothermal synthesis process. The as-prepared novel microsphere films were characterized in detail by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy. Moreover, SnO(2) nanoparticles with 30-80 nm in size covered on the surface of nanosheets/microspheres were also obtained by optimizing the hydrothermal reaction temperature, time, or volume ratio of acetylacetone/H(2)O. The detailed investigations disclose the experimental parameters, such as acetylacetone, NH(4)F, and seed layer play important roles in the morphology of hierarchical SnO(2) microspheres on the FTO glass. The formation process of SnO(2) microspheres is also proposed based on the observations of time dependent samples.
在氟掺杂氧化锡 (FTO) 玻璃衬底上，通过简单的水热合成工艺成功制备了由纳米片组成的分级 SnO2 微球。所制备的新型微球薄膜通过 X 射线衍射 (XRD)、场发射扫描电子显微镜 (FE-SEM)、透射电子显微镜 (TEM)、紫外-可见漫反射光谱进行了详细的表征。此外，通过优化水热反应温度、时间或乙酰丙酮/H2O 的体积比，还获得了尺寸为 30-80nm 的 SnO2 纳米颗粒覆盖在纳米片/微球的表面。详细的研究揭示了实验参数，如乙酰丙酮、NH4F 和种子层在 FTO 玻璃上分级 SnO2 微球的形态中起着重要作用。还根据随时间变化的样品的观察提出了 SnO2 微球的形成过程。
