利用化学溶液沉积法,以Zn(CH3COO)2.2H2O、六次甲基四胺为原料制备了规整而有序的ZnO纳米棒阵列。用FESEM、XRD等考察种子液浓度、反应溶液浓度等对ZnO纳米棒表面形貌、晶粒大小及晶体结构的影响。结果表明,制备的ZnO纳米棒的直径随反应溶液浓度增大而增大,纳米棒垂直于基底沿着(002)面生长。紫外可见吸收光谱表明,ZnO纳米棒对300～400 nm波长范围的光有很强吸收性;在500～700 nm有一个相对比较弱的吸收峰,光致发光谱图中在384 nm处有一个近紫外带边发射峰。
The ordered and ordered ZnO nanorod arrays were prepared by chemical solution deposition method using Zn (CH3COO) 2.2H2O and hexamethylenetetramine as raw materials. The effects of concentration of seed solution and reaction solution on surface morphology, grain size and crystal structure of ZnO nanorods were investigated by FESEM and XRD. The results show that the diameter of the prepared ZnO nanorods increases with the concentration of the reaction solution, and the nanorods grow along the (002) plane perpendicular to the substrate. UV-Vis absorption spectra show that ZnO nanorods have strong absorbency to light in the wavelength range of 300-400 nm, a relatively weak absorption peak at 500-700 nm, and a photoluminescence spectrum at 384 nm Near UV band edge emission peak.
