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.

Radiation emitting device and method of manufacturing a radiation emitting device

A radiation-emitting device may include a radiation-emitting semiconductor chip configured to emit electromagnetic radiation of a first wavelength range from a radiation exit surface, a first phosphor configured to convert electromagnetic radiation of the first wavelength range into electromagnetic radiation of a second wavelength range. The second wavelength range may be or include infrared light. The device may further include an up-converting phosphor configured to convert infrared light of the second wavelength range into visible light.
