摘要 以Zn(NO3)2和NaOH为原料,采用一步水溶液法,不添加任何表面活性剂,在85℃条件下反应30 min制备出形貌规则、结晶良好的三维(3-D)花状ZnO纳米晶体。用X-射线衍射仪(XRD)、场发射电子扫描显微镜(FESEM)、透射电子显微镜(TEM)、高分辨透射电子显微镜(HRTEM)等,分别对产物的结构和形貌进行了表征。通过对花状ZnO生长过程的研究,得出了其在液相中的生长机理。对样品的光致发光(PL)分析显示,Zn O在紫外光区有一个较强的发射,在可见光区有一个较宽的发射;通过在样品中掺杂少量过渡金属离子Co2+可有效屏蔽可见光区的缺陷发光。 Well-crystallized flower-like ZnO nanostructures were prepared via a simple one-step solution method, using zinc nitrate and sodium hydroxide as raw materials. The reaction could be achievedin only 30 min at 85 ℃, without assistance of any surfactant. The structure and morphology of the products were characterized by XRD, FESEM, TEM and HRTEM. Growth mechanism of the flower-like ZnO was studied in detail. Photoluminescence (PL) spectrum of pure ZnO had a strong emission in the ultraviolet region and a broad emission in the visible region. A small amount of Co^2+ doping in the sample can effectively shield the defect luminescence in the visible region.
