摘要

PROBLEM TO BE SOLVED: To provide a crystalline ultrafine particle, which is excellent in dispersibility for compounding it with other materials and has high luminous efficiency and also can be used for manufacturing a transparent stress luminescent material, and a method for manufacturing the same.;SOLUTION: The particle diameter of the crystalline ultrafine particle, which illuminates depending on the changing rate of stress with time, is adjusted to at least 5 nm and not more than 100 nm and the particle is compounded with other materials, e.g. a resin. The crystalline ultrafine particle is prepared by using a reversed micelle, i.e. an aggregate of surfactant molecules whose hydrophilic parts are faced inward and the hydrophobic parts outward in a nonpolar solvent, containing water in which is dissolved ions of a metal as the constituent of the crystalline ultrafine particle, or using a reversed micelle including a precursor ultrafine particle which is contained in the water of the reversed micelle. An artificial luminous hair structure, an artificial luminous skin, an artificial luminous body and an artificial luminous cloth, or the like, are produced by using the above composite materials.;COPYRIGHT: (C)2004,JPO
