Abstract We report on ZnO nanosheets and nanorods synthesized by thermal oxidation of zinc films deposited on carbon fiber surfaces. The structure and optical properties are characterized by x-ray diffraction, scanning electron microscopy and photoluminescence spectrum. An orange-red emission around 683nm is found in the PL spectrum when the sample prepars at 400°C for four hours in air. With annealing temperature increasing from 400°C to 500°C, the blue shift is observed.
