<P>PROBLEM TO BE SOLVED: To provide a phosphor containing a particle structure capable of suppressing the lowering of photoconversion efficiency and provide a lighting device and a display device containing the phosphor. <P>SOLUTION: The phosphor contains a plurality of particles dispersed in a medium 102, each particle contains a core 100 and a coating layer 101 covering the core, the core 100 is composed of a semiconductor absorbing excitation light and emitting light having a wavelength different from the wavelength of the excitation light and the particle has a diameter to cause Mie scattering of the excitation light. A fluorescent material having high photoconversion efficiency can be produced by the method. <P>COPYRIGHT: (C)2004,JPO |
