Abstract Anodic aluminum oxide templates with pore size 70 nm were fabricated using two step anodization processes. BiFeO3 and La doped BiFeO3 nano-particles were synthesized and decorated on anodic aluminum oxide templates to explore its various physical properties. Crystallographic studies reveals the formation of rhombohedral geometry with 166-R-3m space group. Pore size, morphology and elemental compositions of host and decorated templates were analyzed with field emission scanning electron microscopy and energy dispersive X-ray spectroscopy. Optical studies demonstrate enhanced absorption and significant decrease in band gap of host template with decoration of nanoparticles.

BiFeO3和La掺杂BiFeO3纳米颗粒装饰阳极Al2O3多孔模板，两步阳极氧化

摘要 采用两步阳极氧化工艺制备孔径为 70 nm 的阳极氧化铝模板。BiFeO3 和 La 掺杂的 BiFeO3 纳米颗粒被合成并装饰在阳极氧化铝模板上，以探索其各种物理性能。晶体学研究揭示了具有 166-R-3m 空间群的菱形几何结构的形成。使用场发射扫描电子显微镜和能量色散 X 射线光谱分析了主体和装饰模板的孔径、形态和元素组成。光学研究表明，随着纳米颗粒的装饰，主体模板的吸收增强和带隙显着减小。
