| 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.

| Abstract: | 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 directional grown ZnO nano-array is synthesised on the ITO 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 c-axis.... |
