Abstract

A radiation-emitting semiconductor component, having a layer structure (30) which includes an active layer (32) which, in operation, emits radiation with a spectral distribution (60), and electrical contacts (36, 38, 40) for applying a current to the layer structure (30), includes a coating layer (44) which at least partially surrounds the active layer (32) and holds back a short-wave component of the emitted radiation (60).
