The microstructure of layer perovskite La0.9Sr0.1TiO3+δ was investigated by high-resolution transmission electron microscopy and high angle annular dark field image analysis. The mechanism of oxygen vacancy on the lattice structure was revealed. Based on the results by X-ray diffraction, the oxygen-difficient environment effect on the lattice structure leads to the change of axial length and volume contraction in the material. The partial atomic plane rearrangement and dislocation caused by oxygen vacancy and continuous lattice distortion are identified based on high-resolution microscopic and Z-contrast atomic images, respectively. The effective regulation of oxygen vacancy defect shows a great significance on changing the microstructure of materials and further preparation of high-performance perovskite materials.
