| Abstract: | ZnO micro/nanostructures were successfully synthesized without catalyst by direct oxidation of zinc substrate in air.By changing the reaction temperature,ZnO micro/nanosheets 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 280nm.Room temperature photoluminescence measurements reveal a visible emission at 508nm.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. |
