| 中文摘要 | nanocrystalline zro2 fine powders were prepared via the pechini-type sol-gel process followed by annealing from 500 to 1000 degrees c. the obtained zro2 samples were characterized by x-ray diffraction (xrd), field emission scanning electron microscopy (fesem), transmission electron microscopy (tem), electron paramagnetic resonance (epr), and photoluminescence spectra (pl), respectively. the phase transition process from tetragonal (t) to monoclinic (m) was observed for the nanocrystalline zro2 powders in the annealing process, accompanied by the change of their photoluminescence properties. the 500 degrees c annealed zro2, powder with tetragonal structure shows an intense whitish blue emission (lambda(max) = 425 nm) with a wide range of excitation (230-400 nm). this emission decreased in intensity after being annealed at 600 degrees c (t + m-zro2) and disappeared at 700 (t + m-zro2), 800 (t + m-zro2), and 900 degrees c (m-zro2). after further annealing at 1000 degrees c (m-zro2), a strong blue-green emission appeared again (lambda(max) = 470 nm). |
