摘要
The influence of annealing atmosphere on the optical properties of flower-like ZnO is investigated. The flower-like ZnO is composed of nanosheets. Annealing at 500 degrees C results in the increase of the thickness of nanosheets and the enhancement of UV emission. PL spectra results show that the annealing atmosphere affects the visible emission band, which is sensitive to intrinsic and surface defects in the flower-like ZnO. The vibrational properties of the flower-like ZnO annealing in different atmospheres are characterized by Raman spectra.
