The aim of the invention is to produce a fluorescence emitter for the ultraviolet and visible wavelength region, said emitter being chemically stable and non-toxic, or slightly toxic, and forming a suspension in water. To this end, fluorescent nanoparticles are used, the core of said nanoparticles consisting of an oxide ceramic material and the envelope thereof containing a fluorescent material and a polymer or a copolymer. |
