The colloidal crystallization of fine particles is a phenomenon of great interest in connection with the research on the fabrication of photonic crystals. This paper describes a newly proposed method, in which self-arrangement and self-assembly of particles are generated under radiation force, i.e. gradient and scattering forces, and capillary force, respectively. The hexagonal structure in the Fourier-transformed patterns of 2D colloidal crystals shows that the triangular lattice structure is successfully fabricated by the proposed method. This paper is concerned with the principle of newly proposed method, capturing and self-arranging particles by radiation pressure, self-assembling particles by the desiccation process, the enlarging of colloid crystal, and the verification of the triangular lattice structure.
