本文描述了一种简单的无模板水溶液策略，定向附着辅助自组装Sb 2 O3纳米棒和纳米线，形成定义明确的复杂纳米结构。结果表明，在40 °C温度下，不同长度（2 ~ 50 μm）和直径（20 ~ 1000 nm）的Sb_2 O_3纳米棒通过定向附着辅助的端对端自组装过程可轴向自组装成多段同轴纳米线.在80 °C的温度下，通过定向附着辅助的并排自组装过程，直径为10 ~ 30 nm的Sb 2 O 3纳米线可以径向自组装成长度为数百微米，宽度为400 ~ 1000 nm，厚度为20 ~ 60 nm的纳米带。采用XRD、SEM、EDX、TEM、SAED、HRTEM和光致发光等方法对所得自组装纳米结构进行了表征。对纳米结构的形成机理进行了讨论。定向附着辅助自组装策略...
A facile template-free aqueous solution strategy of oriented attachment assisted self-assembly of Sb2O3 nanorods and nanowires into well-defined complex nanostructures is described in this paper. It is demonstrated that at the temperature of 40 °C, the Sb2O3 nanorods with different lengths (2∼50 μm) and diameters (20∼1000 nm) would axially self-assemble into multisegmented coaxial nanowires by an oriented attachment assisted end-to-end self-assembly process. At the temperature of 80 °C, the Sb2O3 nanowires with diameter of 10∼30 nm would radially self-assemble into nanobelts with hundreds of micrometers in length, typically 400∼1000 nm in width and 20∼60 nm in thickness by an oriented attachment assisted side-by-side self-assembly process. The obtained self-assembled nanostructures were analyzed by a series of methods such as XRD, SEM, EDX, TEM, SAED, HRTEM, and photoluminescence. The formation mechanism of the obtained nanostructures was discussed. The oriented attachment assisted self-assembly strategy ...
