Abstract: A light-emitting device includes a carrier, an organic layer sequence arranged on the carrier and having at least one emitter layer containing a light-emitting material configured to emit light of a first wavelength range, a first electrode and a second electrode, and a multiplicity of nanostructures, wherein the nanostructures have a refractive index smaller than a refractive index of the light-emitting material of the emitter layer and at least some of the nanostructures project into the emitter layer or pierce through the emitter layer.

Abstract: An optical element includes a light guide plate with a first major surface and with a second major surface opposite the first major surface and with side faces connecting the first and second major surfaces, wherein the light guide plate includes a matrix material transparent to ultraviolet light in which scattering centers are embedded, at least one light-emitting semiconductor device that couples ultraviolet light into the light guide plate via a side face when in operation, a first filter layer on the first major surface and a second filter layer on the second major surface, wherein the filter layers opaque to ultraviolet light and at least partially transparent to visible light, and a first photochromic layer at least on the first major surface, between the light guide panel and the first filter layer, with a transparency to visible light by ultraviolet light.
