The colloidal crystallization of fine particles is a phenomenon of great interest in connection with the fabrication of photonic crystals. In this report, a new fabrication method is proposed, which is based on self- arrangement and self-assembly of particles generated under the radiation pressure of a focused laser beam, i.e., gradient and scattering forces, and capillary force occurred during the desiccation process, respectively. The hexagonal structure in the Fourier-transformed patterns of 2D colloidal crystals shows that a triangular lattice structure is successfully fabricated by the proposed method. This report is concerned with the principle of newly proposed method, capturing and self-arranging particles by the radiation pressure, self-assembling particles by the capillary force, enlarging the colloidal crystal, and verifying the production of the triangular lattice structure in the crystal of particles.
