Abstract
An optoelectronic semiconductor chip includes a number of active elements arranged at a distance from one another. A carrier is arranged transversely of the active elements. The active elements each have a main axis that extends perpendicularly to the carrier and are oriented parallel to one another. A converter material surrounds the active elements on circumferential faces. The converter material includes a conversion substance or a conversion substance and a matrix material. The active elements each have a central core region that is enclosed by at least two layers such that an active layer encloses the core region and a cover layer encloses the active layer. The core region is formed with a first semiconductor material. The active layer includes a light-emitting material. The cover layer is formed with a second semiconductor material and can have a layer thickness between 0.1 nm and 100 n.
