FLUORESCENT PARTICLE, WITH SEMICONDUCTOR NANOPARTICLES DISPERSED THEREIN, FABRICATED BY THE SOL-GEL PROCESS

摘要

An object of the present invention is to prepare a fine particle with high durability and high brightness, in which semiconductor nanoparticles are assemble. The present invention provides fluorescent fine particles comprising Cd- and Se-containing semiconductor nanoparticles dispersed in silicon-containing fine particles, wherein the average particle size of the silicon-containing fine particles is 20 to 100 nm, and the number of semiconductor nanoparticles dispersed in the silicon-containing fine particles is 10 or more.
