FLUORESCENT ILLUMINATION, GENERATING WHITE LIGHT

FIELD: physics. ^ SUBSTANCE: light-emitting system (1), comprising a radiation source (2), capable of emitting first light with at least a first wavelength spectrum, first fluorescent material (4), capable of absorbing at least partially the first light and emit second light with a second wavelength spectrum, second fluorescent material (8) capable of absorbing at least partially the first light and emit third light with a third wavelength spectrum, in which the first (4) or the second (8) fluorescent material is a polycrystalline ceramic with density higher than 97% of the density of monocrystalline material, and the corresponding other fluorescent material is a powdered luminophor with average particle size 100 nm
