FLUORESCENT SUBSTANCE-SUPPORTED CARRIER, PROCESS FOR PRODUCING THE SAME, AND LIGHT-EMITTING DIODE USING THE FLUORESCENT SUBSTANCE-SUPPORTED CARRIER

摘要

PROBLEM TO BE SOLVED: To achieve a high-brightness fluorescent substance-supported carrier which can increase the amount of a fluorescent substance supported on a substrate.

SOLUTION: A fluorescent substance-supported carrier 10 comprises a substrate 14 formed of nonwoven fabric comprising a number of spaces 16 among fibers 12. A fluorescent substance 18 is supported on the surface of the fibers 12. A light transparent binder 20 containing the fluorescent substance 18 added thereto is filled into the spaces 16 among the fibers 12. In this case, some of the spaces 16 are not filled with the binder 20. There is also provided a fluorescent substance-supported carrier 30 comprising a substrate 32 formed of an elastic porous member such as a sponge having a number of pores 34, and the light transparent binder 20 containing the fluorescent substance 18 added thereto and filled into the pores 34, some of the pores 34 being not filled with the binder 20.
