| 英文摘要 | Hexagonal al-doped zinc oxide (zno) powders with a nominal composition of zn(1-x)al(x)o (0 <= x <= 0.028) were synthesized by the co-precipitation method. the contents of the al element in the samples were measured by the inductively coupled plasma-optical emission spectroscopy (icp-oes) technique. the structures of the zn(1-x)al(x)o (0 <= x <= 0.028) compounds calcined at 1000 and 1200 degrees c have been determined using the rietveld full-profile analysis method. rietveld refinements of the diffraction data indicated that the addition of al initially has a considerably positive effect on the decreasing of the lattice parameters a and c of zn(1-x)al(x)o, but the effect becomes very slight and even negative with the further increase of the al content. the solid solubility limit of al in zno (mole fraction y) is 2.21%, resulting in zn(0.978)al(0.22)o. it seems that when the al content is excessive, al prefers to form a znal(2)o(4) compound with zno, but not to incorporate into the zno lattice to occupy the zn(2+) cites. two phases, [zno] (or al-doped zno) and [znal(2)o(4)], are obviously segregated in zn(1-x)al(x)o while the value of x is larger than 0.024. the uv-vis absorption spectra show that the al-doped zno exhibits a red-shift in the absorption edge without reduced transmission compared with pure zno, which also confirms that al ions enter the zno lattice and form a zn(1-x)al(x)o solid solution. |
