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.
