氧化铝、金和氧化锌构成的类“法国梧桐树”坚果球表面上氧化锌针的生长和特性（英文）

Growth and Characteristics of ZnO Needles in the Surface of “Platanus Occidentalis” Made of Al_2O_3,Au and ZnO

复杂的氧化锌复合材料在光电设备方面有着很大的潜在应用。报道一种特殊"果球"的模拟生长——由Al2O3,Au和ZnO制成的天然"法国梧桐悬铃坚果"。这种"法国梧桐悬铃坚果"表面有许多小的、溅射在Al2O3表面上的金纳米粒子层。通过电沉积技术合成的ZnO针型在金纳米粒子层上可以很好的生长。单色散针(或者六角形纳米柱)的获得有着有不同的分布密度。所制备的样品在扫描电子显微镜(SEM)下观看,像组合起来的"法国梧桐悬铃坚果"。还研究了6 000℃下样品的光致发光(PL)和其他特征。尖锐的束缚激子(BE)的和纵光学声子LO-phonon的光谱线意味着ZnO微纳结构有着高品质的光学特性。

Complex ZnO compound material has great potential applications for optoelectronic devices.In this article,we give report to a simulation growth of a kind of special＂fruiting ball＂——natural＂Platanus Occidentalis＂made of Al2O3,Au and ZnO.The surface of＂Platanus Occidentalis＂has numerous tiny Au seeds on the surface of Al2O3 ball.ZnO needles synthesized by the electrodeposition technique grow well on the Au seed layer.The obtained mono dispersive needles（or hexagonal columns）have different distribution density.The prepared sample looks like the assembled＂Platanus Occidentalis＂in photographs of scanning electron microscopy（SEM）.Photoluminescence（PL）of samples at 6Ktemperature and other characteristics are investigated.The appearance of sharp bound exciton（BE）emission line and the longitudinal optical（LO）-phonon replicas imply that the ZnO nanocolumns are of high optical quality.
