Large-scale, high-purity and uniform tris(8-hydroxyquinoline)aluminium nanoribbons, with average width of 120 nm, thickness of 30 nm, and length up to tens of micrometers, are synthesized via a facile solvothermal route. X-ray powder diffraction, scanning electron microscopy, Fourier transform infrared spectrum, and thermogravimetric analysis--differential thermal analysis are employed to characterize the morphology and structure of the as-prepared products. The excellent photosensitivity and photoresponse of a bundle of nanoribbons are also investigated, which showed that the photoconductivity enhanced by 50 times under irradiation of an incandescence lamp (12 V, 10 W). This work might be useful in the fabrication of photosensor and photoswitch microdevices or nanodevices in the future.
通过简便的溶剂热法合成了大规模、高纯度且均匀的三（8-羟基喹啉）铝纳米带，其平均宽度为120纳米，厚度为30纳米，长度可达数十微米。采用X射线粉末衍射、扫描电子显微镜、傅里叶变换红外光谱以及热重分析-差示热分析来表征所制备产物的形态和结构。还研究了一束纳米带优异的光敏性和光响应，结果表明在白炽灯（12伏，10瓦）照射下，其光电导率提高了50倍。这项工作未来可能在光传感器和光开关微器件或纳米器件的制造中发挥作用。
