摘要

(Cu-Al) co-doped ZnO thin films were deposited on glass substrate by the sol-gel method using the spin coating technique. The crystalline phase structure of the films were analyzed by X-ray diffraction. The photoluminescence spectra of samples were measured by fluorescence spectrophotometer. The results show that these films have a compact hexagonal wurtzitetype structure five peaks have been observed from the PL spectra of the all samples, 367nm (3.38eV), 398nm (3.12eV), 450nm(2.759eV), 483nm(2.57eV) and 468nm(2.653eV). It is concluded that the violet peak may correspond to the excit on emission, the blue emission corresponds to the electron transition from the bottom of the conduction band to the accept or level of zinc vacancy.
