| Abstract: | The crystal structure and infrared absorption spectra of nanocrystallines Dy1-xSrxCoO3-y (0.0≤x≤1.0) were studied. The results show that the latttice parameters were bigger than microcrystallines. The mixed oxides crystallized in orthorhombic (0.0≤x≤0.5) or tetragonal system (0.6≤x≤0.9) or hexagonal system (x=1.0 ). With symmetry centre of crystal structure variation, the spectra bands of nanocrystallines were fissioned. The infrarea absorption spectra of nanocrystallines appeared as quantum size effect. |
