| Abstract: | ZnO micro/nanostructurcs were successfully synthesized without catalyst by direct oxidation of zinc substrate in air. By changing the reaction temperature, ZnO micro/nanoshcets were obtained respectively of high density nanoflake and nanosheets arrays. The diameter of ZnO micro/nanoflake is several micrometers, and the thickness of the micro/nanosheets is about 280 nm. Room temperature photoluminesccnce measurements reveal a visible emission at 508 nm. The present work highlights the promise of the simple direct oxidation process in the high-yield synthesis of high quality semiconductor nanoflake arrays and micro/nanosheets for micro/nano-devices. |
