Abstract:
1. An optoelectronic semiconductor chip comprising a semiconductor layer sequence having an active layer that generates an electromagnetic radiation and a light exit side, and a light coupling-out layer applied to the light exit side, wherein the light coupling-out layer comprises or consists of radiation-inactive nanocrystals composed of a material transmissive to the radiation generated, a refractive index of the radiation-transmissive material for said radiation is at least 1.9, a seed layer is applied at least in places directly on the light exit side, the seed layer, in a plan view, is restricted to a central region of the light exit side, the central region being surrounded by a partial region of the light exit side being free of the seed layer, the nanocrystals are applied directly on a side of the seed layer facing away from the semiconductor layer sequence, and the partial region of the light exit side is free of the nanocrystals, or fewer and/or smaller nanocrystals are applied in the partial region than in the central region of the light exit side.
