Abstract:
An optoelectronic semiconductor chip includes 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 includes of radiation-inactive nanocrystals composed of a material transmissive to the radiation generated, and a refractive index of the radiation-transmissive material for the radiation is at least 1.9.
