Abstract
Provided are a fluorescent particle and a method for manufacturing the same. The fluorescent particle may include a gold nanoparticle; a silica shell covering the gold nanoparticle; and lanthanide group complex particles dispersed in the silica shell. Each of the lanthanide group complex particles may include a lanthanide group ion; a ligand bonded to the lanthanide group ion and including phosphorus; and a ligand bonded to the lanthanide group ion and having a beta diketone functional group. The fluorescent particle is observable with the naked eye and may emit light when ultraviolet light is irradiated. The fluorescent particle may be used for detecting and analyzing biomaterial samples.
