Abstract

A component may include a semiconductor body and a converter layer. The converter layer may have phosphor particles and an electrically conductive matrix material where the phosphor particles are embedded in the matrix material. The converter layer may be arranged on the semiconductor body and may have a plurality of sublayers that are spatially set apart from one another and can be electrically contacted individually. The semiconductor body may have an active zone for producing electromagnetic radiation where the sublayers of the converter layer are designed for local electrical contacting of the active zone.
