Abstract

ZnO hollow microspheres with a shell wall consisting of crystalline ZnO nanosheets were synthesized by using Zn~5~(CO~3~)~2~(OH)~6~ microspheres as spherical templates. Zn~5~(CO~3~)~2~(OH)~6~ microspheres were first fabricated by a solvothermal procedure in an ethylene glycol (EG)–water solution. ZnO microspheres with a hexagonal structure were identified by means of X‐ray diffraction (XRD) and selected‐area electron diffraction (SAED). On the basis of the results, a possible self‐assembly growth mechanism was proposed. It reveals that the EG played an important role in determining the hollow morphologies of Zn~5~(CO~3~)~2~(OH)~6~ structures. In addition, photoluminescence (PL) investigation of ZnO:Eu^3+^ suggested that a direct energy transfer occurred, which was ascribed to the energy transfer from ZnO host to Eu^3+^ ions.
