RADIATION-EMITTING BODY AND METHOD FOR PRODUCING A RADIATION-EMITTING BODY

摘要

The invention relates to a radiation-emitting body, comprising a layer sequence, having an active layer (10) for producing electromagnetic radiation, a reflection layer (50), which reflects the radiation produced, and at least one intermediate layer (40), which is disposed between the active layer (10) and the reflection layer (50). To this end, the active layer (10) on an interface (15) directed toward the reflection layer (50) comprises a rough region, and the reflection layer (50) is substantially planar on an interface (45) directed toward the active layer (10). The invention further relates to a method for producing a radiation-emitting body, wherein a layer sequence is configured on a substrate having an active layer (10) for producing electromagnetic radiation. To this end, an interface (15) is roughened on the active layer (10) and at least one intermediate layer (40) and a reflection layer (50) are configured.
