英文摘要	Zn1-xCuxAl2O4 (x=0, 0.05, 0.10, 0.15, 0.20) nanoparticles with different doping ratios were synthesized by hydrothermal method and heat treatment technology. The crystal structure, morphology, element distribution, binding energy and optical property of the samples were characterized by X-ray diffraction(XRD), field emission transmission electron microscopy(FETEM), Fourier infrared spectrum(FT-IR), X-ray photoelectron spectroscopy(XPS), photoluminescence(PL) and UV-Vis spectroscopy(UV-Vis), and the energy band structure of various defects in ZnAl2O4 structure was calculated by means of the first-principle calculations. The experimental results show that Zn1-xCuxAl2O4 nanoparticles prepared by this method possess spinel structure. The XPS spectra demonstrate that the doped Cu2+ all occupy the tetrahedral sites for Zn0.9Cu0.10Al2O4 samples, the PL spectra show luminescence quenching occurs for Cu2+ doped samples, the UV-Vis result shows the new absorption peak appeared after Cu2+ doped, and the optical properties of the sample are explained by the first principle calculations. © 2019, Science Press.
