利用直流电沉积方法在多孔氧化铝模板的孔洞中生成锌纳米线,在氧气氛围中,于800℃下氧化2 h,将氧化铝中的锌氧化成氧化锌.本研究利用氧气氛围进行锌的氧化,大大提高了传统方法的氧化锌纳米线的制备效率.用场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)和X射线衍射仪(XRD)对其形貌及成分进行表征和分析,结果表明,氧化铝模板的有序孔洞中填充了大尺寸、均匀连续的多晶态氧化锌纳米线.纳米线具有约1000:1的高纵横比,其长度等于氧化铝模板的厚度,直径约为80 nm.光致发光(PL)光谱表明,氧化锌纳米线在504.nm处有由于氧空位引起的较强蓝绿光发射.这为进一步研究ZnO/AAO组装体发学性质和开发新型功能器件提供了基础.

Ordered zinc (Zn) nanowire arrays embedded in anodic aluminum oxide (AAO) templates were prepared by an effective electrodeposition method. Oxygen was used to oxidize the electrodeposited zinc nanowire arrays in the AAO templates. By thermal treatment in an oxygen atmosphere at 800℃ for 2 h, the deposited Zn was completely oxidized. The microstructures and optical properties of the synthesized zinc oxide (ZnO) nanowire arrays were investigated by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and photoluminescence (PL) spectrum analytic apparatus. We found that large scale polycrystalline ZnO nanowire arrays were uniformly assembled in the nanochannels of the AAO template. The nanowires have a very high aspect ratio of about 1000:1 with the length equaling the template thickness and a diameter of about 80 nm. PL measurements of the ZnO/AAO assembly showed a strong green emission at 504 nm, which was attributed to the oxygen vacancy defects of the ZnO nanowires. These results can be used in further studies of the structural and functional properties of electroluminescence devices based on the ZnO/AAO assembly.
