【摘要】 以多孔阳极氧化铝为模板,采用逆向迁移技术,在模板的纳米孔道内反应形成一维纳米结构前驱体,再经后续处理,制得了Sr2CeO4纳米线。通过X射线衍射光谱(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等检测手段对产物进行了表征,结果表明,所得Sr2CeO4纳米线阵列排列整齐,单体纳米线的直径大约为60nm,与所用模板的孔径相当,长度可达30μm。更多还原

【Abstract】 Ordered Sr₂CeO₄ nanowire arrays embedded in anodic alumina membranes（AAM） were fabricated by a converse transport technique that precipitations were shaped into one dimension structure in the hexagonally ordered nanochannels of the AAM and changed into the Sr₂CeO₄ nanowire by the subsequent treatment.The nanowires were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,the transmission electron microscopy（TEM）.The TEM images showed that Sr₂CeO₄ nanowires were about 60 nm in diameter and up to 5μm in length,which correspond to the pore sizes of the applied membranes.The SEM images showed that the Sr₂CeO₄ nanowires were abundant and uniform.更多还原
