<P>PROBLEM TO BE SOLVED: To obtain a designed material exhibiting various kinds of fluorescence when irradiated with ultraviolet rays. <P>SOLUTION: The designed material has a plane from which various kinds of fluorescence are emitted when irradiated with ultraviolet rays and in which at least two luminous materials each exhibiting fluorescence are scattered. One (A) of two luminous materials is composed of a fluorescence emitting material and a high-ultraviolet-reflectivity material (P) and the other (B) is composed of the fluorescence emitting material and a low-ultraviolet-reflectivity material (Q) having the ultraviolet reflectivity lower than that of the high-ultraviolet-reflectivity material (P). <P>COPYRIGHT: (C)2010,JPO&INPIT |
