Abstract
An emitting device comprising a first light emitter adapted to emit a first radiation, and a second light emitter adapted to emit a second radiation different from the first radiation, the first light emitter comprising a first semiconducting structure and a first radiation converter, the second light emitter comprising a second semiconducting structure and a second radiation converter, each semiconducting structure comprising a semiconducting layer adapted to emit a third radiation, each radiation converter comprising a set of particles able to convert the third radiation into the first or second radiation, the particles of the first radiation converter being attached to a surface by a bulk of photosensitive resin and the particles of the second radiation converter being attached to a surface by grafting.
