Filed: 2000-10-18
Abstract: PROBLEM TO BE SOLVED: To provide an ordered-structure material which causes Bragg reflection of light in the region of ultraviolet rays, visible light, and infrared rays, and provide a method for producing the same. SOLUTION: The ordered-structure optical material is produced as follows: the standard deviation of particle diameters of fine grains in a stabilized colloidal solution is controlled to be <=20% of an average particle diameter, and a resultant quasicrystal in the colloidal solution is grown to an arbitrary size by adding to the quasicrystal a vibration at >=0.1 G and <=10 G acceleration and/or a stress vibration of >=20 Pa. At this time, the quasicrystal can be easily grown and its crystal orientation can be easily controlled by using a vessel which has the same shape as a crystal form of a close-packed structure, a shape formed by combining two or more of the crystal forms, or a shape of a partial crystal face of the crystal form. The elasticity of the quasicrystal in the colloidal solution can be controlled with ion concentration or addition of high polymers.  The solidification of the quasicrystal also can be easily performed by filling the gaps among fine particles of the quasicrystal with high polymers or an inorganic material.
