FLUORESCENT PARTICLE INCLUDING LANTHANIDE COMPLEXES

摘要

Provided are fluorescent particles and a manufacturing method thereof. The fluorescent particles comprise: gold nanoparticles; a silica shell covering the gold nanoparticles; and lanthanoid complex particles. The lanthanoid complex particles can respectively include lanthanoid ion; ligand combined with the lanthanoid ion and comprising phosphorus; and ligands combined with the lanthanoid ion and having beta diketone functional groups. The fluorescent particles can be observed with the naked eye and can emit light when irradiating ultraviolet. Also, the fluorescent particles can be used for detecting and analyzing biospecimen materials.
