结合垂直沉积和微隧道毛细管方法, 发展了双基片垂直沉积法, 并利用该方法简单高效地制备了高质量的胶体晶片. 宏观上的亮丽颜色和紫外可见光谱, 以及扫描电子显微镜(SEM)和原子力显微镜(AFM)照片都证明了胶体晶片内部具有高度有序的胶体晶体结构. 在利用该方法构筑胶体晶片的过程中, 毛细力和介质挥发作用对胶体晶体的形成起到了至关重要的作用; 而双基片的限制和保护作用则赋予了胶体晶片较高的稳定性. 通过将不同直径的微球所构筑的胶体晶片进行组合, 我们获得了集多个胶体晶片光学性质于一身的组合胶体晶片. 此外, 该方法制备的胶体晶片不仅可以直接作为光学器件, 还可以作为模板用于构造有序的多孔结构.
Based on the vertical deposition and micro-tunneling capillaries, a vertical bimodal deposition method was developed, and a high quality colloidal wafer was prepared by this method.Microscopic bright color and UV-Vis spectra, as well as scanning electron microscopy (SEM) And atomic force microscopy (AFM) photographs all demonstrate that colloidal crystals have a highly ordered colloidal crystal structure inside. In the process of constructing a colloidal wafer by this method, the capillary force and the volatilization of the medium play a crucial role in the formation of colloidal crystals While the double substrate’s limitation and protection give the colloidal wafer a high stability.A combination of colloidal chips constructed by microspheres with different diameters is combined with the optical properties of multiple colloidal chips In addition, the colloidal wafer prepared by the method can not only be directly used as an optical device, but also be used as a template for constructing an ordered porous structure.
