ABSTRACT:
A fluorescent member includes a plurality of particles dispersed in a medium. Each particle includes a core and a coating layer covering the core. The core is formed of a semiconductor which absorbs excitation light and emits light of a wavelength different from that of the excitation light. Each particle is made to have a particle size for causing Mie scattering with respect to the excitation light. Thus, a fluorescent member excellent in light conversion efficiency can be obtained.
