Radiation-emitting body and method for producing a radiation-emitting body

A radiation-emitting body comprising:

• a layer sequence being free of a substrate and 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 of the layer sequence opposite the first side;
• and
• an interface of the layer sequence which faces the reflection layer and which has a lateral patterning having a plurality of projecting structure elements,
• the reflection layer being connected to the layer sequence such that the reflection layer has a patterning corresponding to the patterning of the interface,
• wherein the reflection layer contains a metal or is formed as a metallic layer, and wherein the interface of the layer sequence is roughened such that the structure elements are distributed irregularly on the interface.
