The morphological variation of ZnO hollow miscrospheres was achieved via a two-step chemical colloidal process. The products were investigated by scanning electron microscopy, high-resolution transmission electron microscopy, Raman scattering spectroscopy, and photoluminescence spectroscopy. A possible evolution mechanism of the ZnO hollow microspheres was discussed. The lattice distortion of ZnO hollow microspheres was found on the edge of the surface. Raman spectra reveal that the E(2)(high) mode of ZnO hollow microspheres is observed at 432 cm(-1). A Raman shift of 5 cm(-1) had taken place compared with the original form of the ZnO microsphere. This study helps us to understand further the structural properties of ZnO hollow microspheres synthesized by a chemical colloidal process.
通过两步化学胶体过程实现了 ZnO 空心微球的形态变化。通过扫描电子显微镜、高分辨率透射电子显微镜、拉曼散射光谱和光致发光光谱对产物进行了研究。讨论了 ZnO 空心微球的可能演化机制。在表面边缘发现了 ZnO 空心微球的晶格畸变。拉曼光谱表明，ZnO 空心微球的 E(2)(high)模式在 432cm(-1)处观察到。与 ZnO 微球的原始形式相比，发生了 5cm(-1)的拉曼位移。这项研究有助于我们进一步了解通过化学胶体过程合成的 ZnO 空心微球的结构特性。
