Abstract
In an embodiment a radiation emitting device includes a semiconductor chip configured to emit electromagnetic radiation of a first wavelength range from a radiation exit surface and a potting comprising a matrix material and a plurality of nanoparticles, wherein a concentration of the nanoparticles in the matrix material decreases starting from the radiation exit surface of the semiconductor chip so that a refractive index of the potting decreases starting from the radiation exit surface of the semiconductor chip, and wherein the nanoparticles are coated with a shell.
