纳米棒超晶格阵列制备数据集

本数据集主要面向非平衡流体中纳米棒组装机理的研究。纳米棒组装过程中经历了分散到聚集的非平衡过程，受到粒子间的热力学因素（如范德华力和静电力）与流体的动力学因素（扩散和对流）的影响，不利于控制组装结构的取向和有序度。通过控制液体的定向退浸润可以调节三相接触线处纳米棒的取向，从而实现纳米棒的有序堆积，获得长程有序的纳米棒超晶格阵列。液桥中的溶剂随着组装不断进行挥发，这是一个标准的非平衡体系。在非平衡态下，量子棒通过“消耗”流体赋予的“负熵”来达成有序组装。我们通过调控非平衡流体中局部熵变化，可以实现取向可控的、长程有序的超晶格结构。通过设计微柱模板的几何形状，可以控制流体流动的方向，从而实现偏振光致发光和偏振光检测。This dataset is targeted primarily at research into the assembly mechanism of nanorods in non-equilibrium fluids. The assembly process of nanorods undergoes a non-equilibrium transition from dispersion to aggregation, which is affected by both thermodynamic interactions between particles (such as van der Waals forces and electrostatic forces) and dynamic factors of the fluid (diffusion and convection), making it difficult to control the orientation and ordering degree of the assembled structures. By controlling the directional dewetting of the liquid, the orientation of nanorods at the three-phase contact line can be adjusted, enabling the ordered stacking of nanorods and obtaining long-range ordered nanorod superlattice arrays. The solvent in the liquid bridge volatilizes continuously as the assembly proceeds, forming a standard non-equilibrium system. In the non-equilibrium state, quantum rods achieve ordered assembly by 'consuming' the 'negative entropy' provided by the fluid. By regulating the local entropy changes in non-equilibrium fluids, we can obtain superlattice structures with controllable orientation and long-range order. By designing the geometric shape of the micropillar templates, the direction of fluid flow can be controlled, thereby enabling polarized photoluminescence and polarized photodetection.
