英文摘要	hexagonal prism-like al-doped zno nanorods were prepared by a coprecipitation method followed by annealing. the effects of al doping and annealing atmosphere on microstructure and optical properties were studied. x-ray diffraction (xrd) results show that the al-doped nanorods have a pure hexagonal wurtzite structure and good crystallinity. field emission scanning electron microscope (fesem) and transmission electron microscope (tem) experiments confirm the rod morphology, single crystal and a-axis preference growth of al-doped zno. energy dispersive x-ray spectroscopy (edx), raman and uv-vis-nir spectra analyses indicate the successful substitutional doping of al in the zno lattice. diffuse reflectance at near-ultraviolet and visible wavelengths analyses indicate the suppression of the optical absorption for al-doped zno compared to pristine zno, which may be related to the resistance to color center formation. the optimal optical properties al-doped zno nanorods (high near-infrared absorption and no formation of the yellow coloration) are reached by combining h-2 atmosphere annealing with al doping.
