中文摘要：

采用醋酸锌和六亚甲基四胺为源,95℃下在生长ZnO籽晶的玻璃衬底上生长了大面积分布均匀的ZnO纳米棒阵列.用X射线衍射仪、扫描电镜和光谱仪分析了纳米棒的结构、形貌和光学性质,研究了溶液中Zn^2＋的浓度及其与六亚甲基四胺的相对比例对纳米棒性能的影响.结果表明,纳米棒的尺寸和性能对溶液中Zn^2＋离子和六亚甲基四胺的浓度及相对比例非常敏感,通过调制他们的浓度与比例可以有效地调制纳米棒的尺寸与性能.当Zn^2＋与六亚甲基四胺的比例一定时,增大Zn^2＋的浓度促进纳米棒的择优生长;在一定的Zn^2＋浓度的溶液中,增大六亚甲基四胺的浓度,ZnO纳米棒的长度和直径都随之增大,ZnO纳米棒有非常良好的c轴择优取向,趋向于沿垂直于衬底的方向生长,同时纳米棒的紫外荧光增强,可见区荧光减弱.350℃下退火20min后,纳米棒阵列的紫外荧光减弱.

英文摘要：

ZnO nanorod arrays were grown on the glass substrates using solution method with hexamethylenetetramine （HMTA） and zinc acetate at 95 ℃. The nanorods properties were characterized by X- ray diffraction, scanning electron microscope and spectrometer. Effects of Zn^2＋ concentration and Zn^2＋ to HMTA ratio on the properties of the nanorods were studied. The rmnorod size and properties are very sensitive to Zn^2＋ concentration and Zn^2＋ to HMTA ratio. Increasing in Zn^2＋ concentration promotes preferential growth along c axis. And increasing in HMTA to Zn^2＋ ratio increases nanorod diameter and length. The nanrods have strong UV emission and weak visible emission. Annealing at 350 ℃ weakens UV emission of the nanorods.
