摘要:

采用超声辅助的溶胶-凝胶阳极氧化铝(AAO)模板法制备Lu2O3纳米线阵列。通过X射线衍射谱(XRD)、能量色散X射线谱(EDX)、扫描以及透射电镜(SEM及TEM)对纳米线阵列的晶体结构和形貌进行表征。结果显示: Lu2O3纳米线阵列的晶相呈纯立方相Lu2O3多晶结构; 纳米线形貌完整、取向一致、粗细均匀, 直径约200 nm。与简单浸泡法相比, 采用的超声辅助技术可有效提高Lu2O3在AAO孔道内的填充度, 填充度接近100%。该方法具有工艺简单、成本低廉、填充度高、重复性好等特点, 不仅可实现大面积Lu2O3纳米线阵列的制备, 而且还可推广到其他材料的纳米线阵列制备。

Abstract:

Lu2O3 nanowire arrays were fabricated by a Sol-Gel anodic aluminum oxide (AAO) template method assisted with ultrasonic treatment. The structure and morphology of Lu2O3 nanowire arrays were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), Energy disperse X-ray spectroscope (EDX), and transmission electron microscope (TEM). The results indicate that the as-prepared nanowire arrays consist of cubic structure of polycrystalline Lu2O3. The Lu2O3 nanowires are parallel to each other and quite uniform in diameter of about 200 nm. The formation mechanism of nanowires is also explored here. It is found that it is easy to evolve Lu2O3 into bamboo-like nanotubes without ultrasonic treatment. Compared with traditional Sol-Gel template method, a good filling of Lu2O3 nanowires embedded in the AAO template can be obtained by improved ultrasonic- assisted technique. Ultrasonic treatment is useful to prepare for other nanowire arrays of different materials.

Key words: ultrasonic treatment, Sol-Gel, AAO template, Lu2O3 nanowire arrays
