A radiation-emitting body comprising a layer sequence having an active region for generating electromagnetic radiation, a coupling-out layer for coupling out the generated radiation, said coupling-out layer being arranged on a first side of the layer sequence, a reflection layer for reflecting the generated radiation, said reflection layer being arranged on a second side opposite the first side, and an interface of the layer sequence which faces the reflection layer and which has a lateral patterning having projecting structure elements, wherein the reflection layer is connected to the layer sequence in such a way that the reflection layer has a patterning corresponding to the patterning of the interface. A method for producing a radiation-emitting body is furthermore specified.
