ZnO nanospindles were synthesized by PVP-assisted hydrothermal growth and ZnO@ZnS core-shell microspindles were successfully fabricated by sulfidation of ZnO nanospindles via a facile chemical synthesis. The as-obtained samples were characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy and fluorescence spectrophotometer. The results showed that the pure ZnO nanospindles were hexagonal wurtzite crystal structure and the ZnS nanoparticles were sphale...
