Abstract

A 100 micrometer sized hierarchical structure consisting of nanosheet can be obtained at the focus of laser beam in nanosheet colloid. This large sized structure was obtained from the colloidal liquid crystallinity of two-dimensional inorganic particles and laser radiation pressure. The scattering force of the laser beam converted the parallel nanosheet alignment to the direction of the incident laser beam. A giant tree-ring-like nanosheet texture is independent of the polarization direction, was organized at the periphery of the focal point.
