Abstract

An optoelectronic semiconductor component and a method for manufacturing an optoelectronic semiconductor component are disclosed. In an embodiment, the component includes a plurality of active regions configured to generate a primary radiation and a plurality of luminescent material particles configured to convert the primary radiation into a secondary radiation, wherein the active regions are arranged spaced apart from each other, wherein each active region has a main extension direction, wherein each active region has a core region comprising a first semiconductor material, wherein each active region has an active layer covering the core region, wherein each active region has a cover layer comprising a second semiconductor material and covering the active layer, wherein at least some of the luminescent material particles are arranged between the active regions, and wherein a diameter of a majority of the luminescent material particles is smaller than a distance between two adjacent active regions.
