Abstract
A radiation-emitting body comprising a layer sequence, having an active layer () for generating electromagnetic radiation, having a reflection layer (), which reflects the generated radiation, and having at least one intermediate layer () arranged between the active layer () and the reflection layer (). In this case, the active layer () has a roughening on an interface () directed toward the reflection layer (), and the reflection layer () is substantially planar at an interface () directed toward the active layer (). Also disclosed is a method for producing a radiation-emitting body, which involves forming a layer sequence on a substrate having an active layer () for generating electromagnetic radiation. In this case, the method comprises roughening an interface () on the active layer (), and forming at least one intermediate layer () and a reflection layer ().
