中文摘要：

为了制备定向生长、光电性能优越的ZnO纳米阵列，改进了一种较为简单的水热方法：首先在ITO玻璃上铺上一层岛状ZnO种子，然后利用水热反应，在ITO玻璃上生长了规则排列的、沿（002）晶轴定向生长的ZnO纳米阵列．并基于XRD、SEM、光致发光光谱等测试揭示了样品的形貌、微结构和发光性能的特征及相互作用机理．分析结果表明，纳米线属于六方纤锌矿结构，具有垂直沿C轴方向择优生长的特征．光致发光光谱测试表明，当ZnO纳米线阵列的取向性较差时，可同时观测到较强的绿光发射和蓝光发射；但是，当ZnO纳米线阵列的取向性明显提高之后，只发射单一的强绿光．进一步分析表明，随着前驱溶液浓度的降低，ZnO纳米线阵列的发光强度呈非线性变化，而纳米线的尺寸单调的变小．

英文摘要：

For the preparation of ZnO nano - arrays with well directional grown and nice photoelectric properties, firstly a simple method to spread ZnO seeds on ITO glass was used, then during the hydrothermal reaction, well directiona/ grown ZnO nano -array is synthesised on the /TO glass, and then test the micro - appearance by SEM, wurtzite structure by XRD, optical properties by PL, study the mutual mechanism. The results show that the nanowire - arrays are the wurtzite structure, and has a property of orienting with the e - axis. The PL spectra shows that when ZnO nanowire - arrays has a mess orientation strong green emission and, violet emission is able to he tested; but when the orientation is improved obviously, only strong green light emission is tested . The further analysis indicates that the emission intensity of ZnO nanowire - arrays ehange nonlinearly with the decrease concentration of precursor solutions, while the size of nanowire reduces.
