摘要 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。 The uniform bundles of ZnO nanowires have been synthesized in large-scale by an improved microemulsion method at a low temperature in the presence of dodecyl benzene sulfonic acid sodium salt (DBS) and hydrazine. The products are characterized using X-ray diffraction (XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), high-resolution transmission electron microscopy(HRTEM) and selected-area electron diffraction pattern (SAED). The as-grown ZnO nanowires are uniform with a diameter of 30-50 nm and length about 1.5-2.5 μm and oriented attached as bundles. The nanowires are single crystal and preferentially grew along the [002] facet. The sharp UV emission shifted to 386 nm with a full width at half maximum (FWHM) of about 20 nm
