摘　　要：用显微拉曼光谱对纯铁氧化法生长的新铁氧化物材料进行了结构鉴认和成分分析。实验和分析清楚地证明样品的顶层长出了纳米结构的α Fe2 O3 ,中间层的主要成分是Fe3 O4,底层在测量时很可能是与α Fe2 O3Micro-Raman spectroscopy was used to investigate the chemical composition, microstructure and crystalline phase of an iron oxide sample with three-layer macro-structure prepared by iron oxidation. Two laser lines of 514 and 633 nm with a power of 0.5 mW on the sample were employed to excite the Raman spectra. Comparing the sample spectra to that of bulk alpha-Fe2O3, the sample Raman peaks were assigned. And it was found for the top-layer that the Raman frequencies were down shifted and the peak widths broadened. Therefore we verified that the top-layer of the verified sample is a nano-structure alpha-Fe2O3, the main component of the middle-layer is Fe3O4 and the bottom-layer is most like bulk alpha-Fe2O3.
