利用水合醋酸锌粉作为锌源,十二烷基苯磺酸钠(DBS)作表面活性剂,通过改进的微乳液法,在较低温度下制备出形貌均一的ZnO纳米线束.对样品进行了XRD图谱、扫描电镜(TEM)、透射电镜(SEM)、高分辨透射电镜(HRTEM)、选区电子衍射像(SAED)和光致发光(PL)性能研究.该线束由直径约为30～50 nm,长度约为1.5～2.5μm的ZnO纳米线定向聚集组成,其中,纳米线为六方纤锌矿结构的ZnO单晶纳米线,并且沿(002)晶面生长.其激发发射光谱显示样品存在两个发射带:近紫外发射峰(386 nm)和一个黄绿光的发光区,紫外半峰宽约为20 nm,纳米线的尺寸和形貌对光谱峰宽和谱峰位置有一定影响.
