Abstract
By using a simple and mild two-step water-bath method,a large area of flower-like selfsupporting Ag-doped ZnO nanoarrays were fabricated. Field emission scanning electron microscopy( FESEM),energy dispersive X-ray spectrometer( EDS),X-ray diffraction( XRD),room temperature and temperature depend photoluminescence( PL) were used to characterize the morphology, crystalline quality and optical properties of the samples. The emission related to acceptor located at 3. 360 eV and 3. 315 eV can be observed at low temperature( 85 K),and the theoretical calculated acceptor binding energy is 118 meV. In temperature depend PL spectra,the calculated values of FA emission agree well with the theoretical model.
