中文摘要：

研究在乙二醇和NH4F混合电解液中通过阳极氧化Ti-xFe合金制备自组装、高度有序的Ti-Fe-O纳米管阵列薄膜,以及该薄膜的Uv-Vis（200-1000nm）光响应性能。薄膜形貌的关键影响因素为Fe含量。随着Fe含量的增加,纳米管阵列的表面越平整,而纳米管的底部越无序。GAXRD和光响应测试表明,Fe成功地掺杂在纳米管层中,并导致纳米管具有明显的可见光响应。利用该工艺在Ti-12Fe合金表面制备的样品在可见光谱范围内具有大的光响应能力。

英文摘要：

We reported the fabrication of self-organized,vertically oriented Ti-Fe-O nanotube array films grown by anodization of Ti-xFe alloys in an ethylene glycol and NH4F mixed electrolyte and their Uv-Vis spectrum （200-1000 nm） photoresponse properties. The key factor affecting the morphology is the Fe content. The higher the Fe content is,the flatter the nanotubes surface is,and the more disorder the bottom surface appears. XRD and photoresponse measurements demonstrate the realizable iron doping of the nanotube layers,which leads to a significant visible photoresponse. The Ti-12Fe sample prepared has a high photoresponse in visible range of the spectrum.
