【摘要】 用两步阳极氧化法在0.3 mol.L-1草酸中制备了高度有序、具有纳米级孔洞的阳极氧化铝有序阵列模板.用场发射扫描电镜、X射线衍射及荧光光谱对其进行了结构和性能表征.实验结果表明多孔氧化铝模板的蓝发光带是由氧空位缺陷所引起的.对氧化铝模板的形成机理进行了分析,认为它的形成机理可以通过综合参考溶解模型和机械应力模型加以解释,并且电渗在阳极氧化膜的生长过程中起着重要作用.更多还原

【Abstract】 Anodic aluminum oxide（AAO） template with hexagonal closely packed arrays of nanometer-sized pores was successfully fabricated through a two-step electrochemical anodizing process in 0.3 mol\5L^-1(H₂C₂O₄.) The AAO template was characterized by field emission scanning electron microscope,X-ray diffraction and fluorescence spectroscopy.The experiment results confirmed that the blue PL band of AAO template could be attributed to the oxygen-related defect centers.In addition,the model that the pores growth based on the electric field distribution at the pore tips and the model mechanical stress at the metal/oxide interface promoting the formation of ordered hexagonal pore arrays serve to explain the formation mechanism of anodic aluminum oxide template.更多还原
