摘要
在917℃的温度下,我们利用氧化锌和石墨作为混合物源,通过无催化气—固生长,获得了超长的氧化锌纳米线。氧化锌纳米线长度超过100μm,直径约100-300 nm,具有统一的六边形截面。单根超长氧化锌纳米线生长在长度大约5μm,直径大约600 nm的氧化锌纳米塔上。这种形貌突变和超长纳米线的生长是由于混合物源表面所形成的氧化锌硬层所导致的。锌蒸气和氧气的局部浓度对超长的氧化锌纳米线的形成至关重要。通过这种无催化生长的的超长的氧化锌纳米线具有很好的重复性,在氧化锌纳米器件和纳米电路上展现了广阔前景。
The ultralong ZnO nanowires have been obtained by using ZnO and graphite as the mixture source viathe catalyst-free vapor-solid(VS) process at 917℃.The ZnO nanowires are over 100 um in length and~100-300 nm in diameter with uniform hexagonal cross section.The single ultralong ZnO nanowire grows on the top of one ZnO nanotower with the length of ~5 um and the diameter of ~600 nm.The formation of a ZnO hard layer on the surface of the mixture source is responsible for the abruptmorphology change and the growth of the ultralong nanowires.The local concentration of theZn vaporand the oxygen are found to be critical for the formation of the ultralong ZnO nanowires.The catalyst-free growth of the ultralong ZnO nanowire was carried out with good repeatability,showing a promising potentialfor the development of the ZnO based nanodevices and nanocircuit.
