STRAHLUNGSEMITTIERENDES BAUTEIL UND VERFAHREN ZUR HERSTELLUNG EINES STRAHLUNGSEMITTIERENDEN BAUTEILS

The invention relates to a radiation-emitting component comprising a substrate formed with sapphire and/or AIN. A semiconductor layer sequence is applied to the substrate. A radiation decoupling layer is arranged on the side of the substrate facing away from the semiconductor layer sequence, wherein the semiconductor layer sequence comprises an active region for generating electromagnetic radiation, and wherein, for the electromagnetic radiation generated by the active region, the radiation decoupling layer has a refractive index between the refractive index of the substrate and the refractive index of the medium surrounding the component. The radiation decoupling layer is based on quartz glass. The invention also relates to a method for producing an optoelectronic component.
