Disclosed is a method of manufacturing lanthanide fluores cent silica nanoparticles,
including a complex synthesis step of synthesizing a silane-lanthanide chelate complex, an
emulsion formation step of forming a water-in-oil micro emulsion by dispersing micelles, the
water-phase core of which is introduced with the silane-lanthanide chelate com plex, in an
oil-phase solvent, a silica introduction step of introducing a silica precursor into the
microemulsion, and a nanoparticle synthesis step of synthesizing fluorescent silica …
